Mr. Justice Brennan
delivered the opinion of the Court.
At issue in this case is the constitutionality under the First and Fourteenth Amendments of a state statute that generally bars picketing of residences or dwellings, but exempts from its prohibition “the peaceful picketing of a place of employment involved in a labor dispute.”
I
On September 6, 1977, several of the appellees, all of whom are members of a civil rights organization entitled the Committee Against Racism, participated in a peaceful demonstration on the public sidewalk in front of the home of Michael Bilandic, then Mayor of Chicago, protesting his alleged failure to support the busing of schoolchildren to achieve racial integration. They were arrested and charged with unlawful residential picketing in violation of Ill. Rev. Stat., ch. 38, § 21.1-2 (1977), which provides:
“It is unlawful to picket before or about the residence or dwelling of any person, except when the residence or dwelling is used as a place of business. However, this Article does not apply to a person peacefully picketing his own residence or dwelling and does not prohibit the peaceful picketing of a place of employment involved in a labor dispute or the place of holding a meeting or assembly on premises commonly used to discuss subjects of general public interest.”
Appellees pleaded guilty to the charge and were sentenced to periods of supervision ranging from six months to a year.
In April 1978, appellees commenced this lawsuit in the United States District Court for the Northern District of Illinois, seeking a declaratory judgment that the Illinois residential picketing statute is unconstitutional on its face and as applied, and an injunction prohibiting defendants — various state, county, and city officials — -from enforcing the statute. Appellees did not attempt to attack collaterally their earlier state-court convictions, but requested only prospective relief. Alleging that they wished to renew their picketing in residential neighborhoods but were inhibited from doing so by the threat of criminal prosecution under the residential picketing statute, appellees challenged the Act under the First and Fourteenth Amendments as an overbroad, vague, and, in light of the exception for labor picketing, impermissible content-based restriction on protected expression. The District Court, ruling on cross-motions for summary judgment, denied all relief. Brown v. Scott, 462 F. Supp. 518 (1978).
The Court of Appeals for the Seventh Circuit reversed. Brown v. Scott, 602 F. 2d 791 (1979). Discerning “no principled basis” for distinguishing the Illinois statute from a similar picketing prohibition invalidated in Police Department of Chicago v. Mosley, 408 U. S. 92 (1972), the court concluded that the Act’s differential treatment of labor and nonlabor picketing could not be justified either by the important state interest in protecting the peace and privacy of the home or by the special character of a residence that is also used as a “place of employment.” Accordingly, the court held that the statute, both on its face and as applied to appellees, violated the Equal Protection Clause of the Fourteenth Amendment. We noted probable jurisdiction. 444 U. S. 1011 (1980). We affirm.
II
As the Court of Appeals observed, this is not the first instance in which this Court has had occasion to consider the constitutionality of an enactment selectively proscribing peaceful picketing on the basis of the placard’s message. Police Department of Chicago v. Mosley, supra, arose out of a challenge to a Chicago ordinance that prohibited picketing in front of any school other than one “involved in a labor dispute.” We held that the ordinance violated the Equal Protection Clause because it impermissibly distinguished between labor picketing and all other peaceful picketing without any showing that the latter was “clearly more disruptive” than the former. 408 U. S., at 100. Like the Court of Appeals, we find the Illinois residential picketing statute at issue in the present case constitutionally indistinguishable from the ordinance invalidated in Mosley.
There can be no doubt that in prohibiting peaceful picketing on the public streets and sidewalks in residential neighborhoods, the Illinois statute regulates expressive conduct that falls within the First Amendment’s preserve. See, e. g., Thornhill v. Alabama, 310 U. S. 88 (1940); Gregory v. Chicago, 394 U. S. 111, 112 (1969); Shuttlesworth v. Birmingham, 394 U. S. 147, 152 (1969). “Wherever the title of streets and parks may rest, they have immemorially been held in trust for the use of the public and, time out of mind, have been used for purposes of assembly, communicating thoughts between citizens, and discussing public questions.” Hague v. CIO, 307 U. S. 496, 515 (1939) (opinion of Roberts, J.). “‘[SJtreets, sidewalks, parks, and other similar public places are so historically associated with the exercise of First Amendment rights that access to them for the purpose of exercising such rights cannot constitutionally be denied broadly and absolutely.’” Hudgens v. NLRB, 424 U. S. 507, 515 (1976) (quoting Food Employees v. Logan Valley Plaza, 391 U. S. 308, 315 (1968)).
Nor can it be seriously disputed that in exempting from its general prohibition only the “peaceful picketing of a place of employment involved in a labor dispute,” the Illinois statute discriminates between lawful and unlawful conduct based upon the content of the demonstrator’s communication. On its face, the Act accords preferential treatment to the expression of views on one particular subject; information about labor disputes may be freely disseminated, but discussion of all other issues is restricted. The permissibility of residential picketing under the Illinois statute is thus dependent solely on the nature of the message being conveyed.
In these critical respects, then, the Illinois statute is identical to the ordinance in Mosley, and it suffers from the same constitutional infirmities. When government regulation discriminates among speech-related activities in a public forum, the Equal Protection Clause mandates that the legislation be finely tailored to serve substantial state interests, and the justifications offered for any distinctions it draws must be carefully scrutinized. Police Department of Chicago v. Mosley, 408 U. S., at 98-99, 101; see United States v. O’Brien, 391 U. S. 367, 376-377 (1968); Williams v. Rhodes, 393 U. S. 23, 30-31 (1968); Dunn v. Blumstein, 405 U. S. 330, 342-343 (1972); San Antonio Independent School Dist. v. Rodriguez, 411 U. S. 1, 34, n. 75 (1973). As we explained in Mosley: “Chicago may not vindicate its interest in preventing disruption by the wholesale exclusion of picketing on all but one preferred subject. Given what Chicago tolerates from labor picketing, the excesses of some nonlabor picketing may not be controlled by a broad ordinance prohibiting both peaceful and violent picketing. Such excesses 'can be controlled by narrowly drawn statutes/ Saia v. New York, 334 U. S., at 562, focusing on the abuses and dealing evenhandedly with picketing regardless of subject matter.” 408 U. S., at 101-102. Yet here, under the guise of preserving residential privacy, Illinois has flatly prohibited all nonlabor picketing even though it permits labor picketing that is equally likely to intrude on the tranquility of the home.
Moreover, it is the content of the speech that determines whether it is within or without the statute’s blunt prohibition. What we said in Mosley has equal force in the present case:
“The central problem with Chicago’s ordinance is that it describes permissible picketing in terms of its subject matter. Peaceful picketing on the subject of a school’s labor-management dispute is permitted, but all other peaceful picketing is prohibited. The operative distinction is the message on a picket sign. . . . Any restriction on expressive activity because of its content would completely undercut the 'profound national commitment to the principle that debate on public issues should be uninhibited, robust, and wide-open.’ New York Times Co. v. Sullivan, [376 U. S. 254], 270.
“Necessarily, then, under the Equal Protection Clause, not to mention the First Amendment itself, government may not grant the use of a forum to people whose views it finds acceptable, but deny use to those wishing to express less favored or more controversial views. And it may not select which issues are worth discussing or debating in public facilities. There is an ‘equality of status in the field of ideas,’ and government must afford all points of view an equal opportunity to be heard. Once a forum is opened up to assembly or speaking by some groups, government may not prohibit others from assembling or speaking on the basis of what they intend to say. Selective exclusions from a public forum may not be based on content alone, and may not be justified by reference to content alone.” Id., at 95-96 (citations and footnote omitted)
III
Appellant nonetheless contends that this case is distinguishable from Mosley. He argues that the state interests here are especially compelling and particularly well served by a statute that accords differential treatment to labor and non-labor picketing. We explore in turn each of these interests, and the manner in which they are said to be furthered by this statute.
A
Appellant explains that whereas the Chicago ordinance sought to prevent disruption of the schools, concededly a “substantial” and “legitimate” governmental concern, see id., at 99, 100, the Illinois statute was enacted to ensure privacy in the home, a right which ■ appellant views as paramount in our constitutional scheme. For this reason, he contends that the same content-based distinctions held invalid in the Mosley context may be upheld in the present case.
We find it unnecessary, however, to consider whether the State’s interest in residential privacy outranks its interest in quiet schools in the hierarchy of societal values. For even the most legitimate goal may not be advanced in a constitutionally impermissible manner. And though we might agree that certain state interests may be so compelling that where no adequate alternatives exist a content-based distinction— if narrowly drawn — would be a permissible way of furthering those objectives, cf. Schenck v. United States, 249 U. S. 47 (1919), this is not such a case.
First, the generalized classification which the statute draws suggests that Illinois itself has determined that residential privacy is not a transcendent objective: While broadly permitting all peaceful labor picketing notwithstanding the disturbances it would undoubtedly engender, the statute makes no attempt to distinguish among various sorts of nonlabor picketing on the basis of the harms they would inflict on the privacy interest) The apparent overinclusiveness and under-inclusiveness of the statute’s restriction would seem largely to undermine appellant’s claim that the prohibition of all non-labor picketing can be justified by reference to the State’s interest in maintaining domestic tranquility.
More fundamentally, the exclusion for labor picketing cannot be upheld as a means of protecting residential privacy for the simple reason that nothing in the content-based labor-nonlabor distinction has any bearing whatsoever on privacy. Appellant can point to nothing inherent in the nature of peaceful labor picketing that would make it any less disruptive of residential privacy than peaceful picketing on issues of broader social concern. Standing alone, then, the State’s asserted interest in promoting the privacy of the home is not sufficient to save the statute.
B
The second important objective advanced by appellant in support of the statute is the State’s interest in providing special protection for labor protests. He maintains that federal and state law has long exhibited an unusual concern for such activities, and he contends that this solicitude may be furthered by a narrowly drawn exemption for labor picketing.
The central difficulty with this argument is that it forthrightly presupposes that labor picketing is more deserving of First Amendment protection than are public protests over other issues, particularly the important economic, social, and political subjects about which these appellees wish to demonstrate. We reject that proposition. Cf. T. Emerson, The System of Freedom of Expression 444-449' (1970) (suggesting that nonlabor picketing is more akin to pine expression than labor picketing and thus should be subject to fewer restrictions). Public-issue picketing, “an exercise of . . . basic constitutional rights in their most pristine and classic form,” Edwards v. South Carolina, 372 U. S. 229, 235 (1963), has always rested on the highest rung of the hierarchy of First Amendment values: “The maintenance of the opportunity for free political discussion to the end that government may be responsive to the will of the people and that changes may be obtained by lawful means, an opportunity essential to the security of the Republic, is a fundamental principle of our constitutional system.” Stromberg v. California, 283 U. S. 359, 369 (1931). See generally A. Meiklejohn, Free Speech and Its Relation to Self-Government (1948). While the State’s motivation in protecting the First Amendment rights of employees involved in labor disputes is commendable, that factor, without more, cannot justify the labor picketing exemption.
C
Appellant’s final contention is that the statute can be justified by some combination of the preceding objectives. This argument is fashioned on two different levels. In its elemental formulation, it posits simply that a distinction between labor and nonlabor picketing is uniquely suited to furthering the legislative judgment that residential privacy should be preserved to the greatest extent possible without also compromising the special protection owing to labor picketing. In short, the statute is viewed as a reasonable attempt to accommodate the competing rights of the homeowner to enjoy his privacy and the employee to demonstrate over labor disputes. But this attempt to justify the statute hinges on the validity of both of these goals, and we have already concluded that the latter — the desire to favor one form of speech over all others — is illegitimate.
The second and more complex formulation of appellant’s position characterizes the statute as a carefully drafted attempt to prohibit that picketing which would impinge on residential privacy while permitting that picketing which would not. In essence, appellant asserts that the exception for labor picketing does not contravene the State’s interest in preserving residential tranquility because of the unique character of a residence that is a “place of employment.” By “inviting” a worker into his home and converting that dwelling into a place of employment, the argument goes, the resident has diluted his entitlement to total privacy. In other words, he has “waived” his right to be free from picketing with respect to disputes arising out of the employment relationship, thereby justifying the statute’s narrow labor exception at those locations.
The flaw in this argument is that it proves too little. Numerous types of peaceful picketing other than labor picketing would have but a negligible impact on privacy interests, and numerous other actions of a homeowner might constitute “nonresidential” uses of his property and would thus serve to vitiate the right to residential privacy. For example, the resident who prominently decorates his windows and front yard with posters promoting the qualifications of one candidate for political office might be said to “invite” a counter-demonstration from supporters of an opposing candidate. Similarly, a county chairman who uses his home to meet with his district captains and to discuss some controversial issue might well expect that those who are deeply concerned about the decision the chairman will ultimately reach would want to make their views known by demonstrating outside his home during the meeting. And, with particular regard to the facts of the instant case, it borders on the frivolous to suggest that a resident who invites a repairman into his home to fix his television set has “waived” his right to privacy with respect to a dispute between the repairman and the local union, but that the official who has voluntarily chosen to enter the public arena has not likewise “waived” his right to privacy with respect to a challenge to his views on significant issues of social and economic policy.
IV
We therefore conclude that appellant has not successfully distinguished Mosley. We are not to be understood to imply, however, that residential picketing is beyond the reach of uniform and nondiscriminatory regulation. For the right to communicate is not limitless. E. g., Cox v. Louisiana, 379 U. S. 536, 554-555 (1965); Cox v. Louisiana, 379 U. S. 559, 563-564 (1965). Even peaceful picketing may be prohibited when it interferes with the operation of vital governmental facilities, see, e. g., ibid, (picketing or parading prohibited near courthouses); Adderley v. Florida, 385 U. S. 39 (1966) (demonstrations prohibited on jailhouse grounds), or when it is directed toward an illegal purpose, see, e. g., Teamsters v. Vogt, Inc., 354 U. S. 284 (1957) (prohibition of picketing directed toward achieving “union shop” in violation of state law).
Moreover, we have often declared that “[a] state or municipality may protect individual privacy by enacting reasonable time, place, and manner regulations applicable to all speech irrespective of content.” Erznoznik v. City of Jacksonville, 422 U. S. 205, 209 (1975) (emphasis supplied). See, e. g., Cox v. New Hampshire, 312 U. S. 569 (1941); Kovacs v. Cooper, 336 U. S. 77 (1949); Poulos v. New Hampshire, 345 U. S. 395 (1953); Cox v. Louisiana, 379 U. S., at 554; Grayned v. City of Rockford, 408 U. S. 104 (1972). In sum, “no mandate in our Constitution leaves States and governmental units powerless to pass laws to protect the public from the kind of boisterous and threatening conduct that disturbs the tranquility of spots selected by the people either for homes, wherein they can escape the hurly-burly of the outside business and political world, or for public and other buildings that require peace and quiet to carry out their functions, such as courts, libraries, schools, and hospitals.” Gregory v. Chicago, 394 U. S. 111, 118 (1969) (Black, J., concurring).
Preserving the sanctity of the home, the one retreat to which men and women can repair to escape from the tribulations of their daily pursuits, is surely an important value. Our decisions reflect no lack of solicitude for the right of an individual “to be let alone” in the privacy of the home, “sometimes the last citadel of the tired, the weary, and the sick.” Id., at 125 (Black, J., concurring). See generally Stanley v. Georgia, 394 U. S. 557 (1969); Rowan v. United States Post Office Dept., 397 U. S. 728 (1970); FCC v. Pacifica Foundation, 438 U. S. 726 (1978); Payton v. New York, 445 U. S. 573 (1980). The State’s interest in protecting the well-being, tranquility, and privacy of the home is certainly of the highest order in a free and civilized society. “ ‘The crucial question, however, is whether [the Illinois’ statute] advances that objective in a manner consistent with the command of the Equal Protection Clause.’ Reed v. Reed, 404 U. S. [71], 76 [(1971)].” Police Department of Chicago v. Mosley, 408 U. S., at 99’. And because the statute discriminates among pickets based on the subject matter of their expression, the answer must be “No.”
The judgment of the Court of Appeals is
Affirmed
A violation of § 21.1-2 is a “Class B” misdemeanor punishable by a fine of up to $500 and imprisonment for not more than six months. See Ill. Rev. Stat., ch. 38, §§ 21.1-3, 1005-8-3, 1005-9-1 (1977).
At least four other States have enacted antiresidential picketing laws similar in form to this statute. See Ark. Stat. Ann. §§ 41-2966 to 41-2968 (1977); Conn. Gen. Stat. § 31-120 (1979); Haw. Rev. Stat. § 379A-1 (1976); Md. Ann. Code, Art. 27, § 580A (1976). Connecticut’s law has been construed to permit all picketing in a residential area except for labor picketing that is not conducted at the situs of a labor dispute. State v. Anonymous, 6 Conn. Cir. 372, 274 A. 2d 897 (App. Div. 1970); DeGregory v. Giesing, 427 F. Supp. 910 (Conn. 1977) (three-judge court). The Maryland statute was declared unconstitutional by the Maryland Court of Appeals in State v. Schuller, 280 Md. 305, 372 A. 2d 1076 (1977). See also People Acting Through Community Effort v. Doorley, 468 F. 2d 1143 (CA1 1972) (invalidating municipal ordinance virtually identical to the Illinois residential picketing statute); but see Wauwatosa v. King, 49 Wis. 2d 398, 182 N. W. 2d 530 (1971) (upholding validity of similar ordinance).
Because the Court of Appeals concluded that the labor dispute exception was not severable from the remainder of the statute, it invalidated the enactment in its entirety. Cf. State v. Schuller, supra, at 318-321, 372 A. 2d, at 1083-1084. The court therefore found it unnecessary to consider the constitutionality under the First Amendment of a statute that prohibited all residential picketing. Brown v. Scott, 602 F. 2d 791, 795, n. 6 (1979). Because we find the present statute defective on equal protection principles, we likewise do not consider whether a statute barring all residential picketing regardless of its subject matter would violate the First and Fourteenth Amendments.
Chicago Municipal Code, ch. 193-1 (i) (1968), provided:
“A person commits disorderly conduct when he knowingly:
“(i) Pickets or demonstrates on a public way within 150 feet of any primary or secondary school building while the school is in session and one-half hour before the school is in session and one-half hour after the school session has been concluded, provided that this subsection does not prohibit the peaceful picketing of any school involved in a labor dispute. . . (Emphasis supplied.)
The Illinois residential picketing statute apparently has not been construed by the state courts. Throughout this litigation, however, all parties and the courts below have interpreted the statutory exception for “peaceful picketing of a place of employment involved in a labor dispute” as embodying the additional requirement that the subject of the picketing be related to the ongoing labor dispute. Police Department of Chicago v. Mosley, 408 TJ. S. 92 (1972), was premised upon an identical construction. See id., at 94, n. 2 (statutory exemption for “the peaceful picketing of any school involved in a labor dispute” applies only to labor picketing of a school involved in such a dispute).
The District Court read the labor exception in this statute as creating two separate classifications: one between “places of employment” and all other “residences,” and a second between “places of employment involved in a labor dispute” and “places of employment not involved in a labor dispute.” The court held that the first classification was a permissible content-neutral regulation of the location of picketing. And although recognizing that the second distinction may well be based on the subject matter of the demonstration, see n. 4, supra, the court held that appellees lacked standing to challenge it because they were not seeking to picket “a place of employment,” and thus would not have benefitted from a determination that the second classification was unconstitutional. Brown v. Scott, 462 F. Supp. 518, 534-535 (1978).
The Court of Appeals, in reversing the District Court, refused to adopt the lower court’s interpretation of the statute. Rather, it read the “place of employment” exception to divide “residences and dwellings” into but two categories — those at which picketing is lawful (i. e., all places of employment involved in labor disputes) and those at which it is unlawful (*. e., all other residences and dwellings). Brown v. Scott, 602 F. 2d, at 793-794. We accept the construction of the Court of Appeals. Appellees sought to picket at a residence and were denied permission to do so. They clearly have standing to attack the statutory classification on which that denial was premised. Indeed, appellant does not challenge the Court of Appeals’ interpretation of the statute, Tr. of Oral Arg. 13, and he concedes that this restriction is content-based, id., at 21.
It is, of course, no answer to assert that the Illinois statute does not discriminate on the basis of the speaker’s viewpoint, but only on the basis of the subject matter of his message. “The First Amendment’s hostility to content-based regulation extends not only to restrictions on particular viewpoints, but also to prohibition of public discussion of an entire topic.” Consolidated Edison Co. v. Public Service Comm’n, post, at 537.
Mosley was neither the Court’s first nor its last pronouncement that the First and Fourteenth Amendments forbid discrimination in the regulation of expression on the basis of the content of that expression. See Cox v. Louisiana, 379 U. S. 536, 581 (1965) (Black, J., concurring):
“Standing, patrolling, or marching back and forth on streets is conduct, not speech, and as conduct can be regulated or prohibited. But by specifically permitting picketing for the publication of labor union views, Louisiana is attempting to pick and choose among the views it is willing to have discussed on its streets. It thus is trying to prescribe by law what matters of public interest people whom it allows to assemble on its streets may and may not discuss. This seems to me to be censorship in a most odious form, unconstitutional under the First and Fourteenth Amendments. And to deny this appellant and his group use of the streets because of their views against racial discrimination, while allowing other groups to use the streets to voice opinions on other subjects, also amounts, I think, to an invidious discrimination forbidden by the Equal Protection Clause of the Fourteenth Amendment.”
See also Erznoznik v. City of Jacksonville, 422 U. S. 205, 209, 215 (1975); Hudgens v. NLRB, 424 U. S. 507, 520 (1976); Madison Joint School District No. 8 v. Wisconsin Employment Relations Comm’n, 429 U. S. 167, 175-176 (1976); First National Bank of Boston v. Bellotti, 435 U. S. 765, 784-785 (1978); Consolidated Edison Co. v. Public Service Comm’n, post, at 536-538.
The importance which the State attaches to the interest in maintaining residential privacy is reflected in the Illinois Legislature’s finding accompanying the residential picketing statute:
“The Legislature finds and declares that men in a free society have the right to quiet enjoyment of their homes; that the stability of community and family life cannot be maintained unless the right to privacy and a sense of security and peace in the home are respected and encouraged; that residential picketing, however just the cause inspiring it, disrupts home, family and communal life; that residential picketing is inappropriate in our society, where the jealously guarded rights of free speech and assembly have always been associated with respect for the rights of others. For these reasons the Legislature finds and declares this Article to be necessary.” IE. Rev. Stat., ch. 38, §21.1-1 (1977).
Cf. Kalven, The Concept of the Public Forum: Cox v. Louisiana, 1965 Sup. Ct. Rev. 1, 29 (quoted in Young v. American Mini Theatres, Inc., 427 U. S. 50, 67, n. 27 (1976) (opinion of Stevens, J.)): “If some groups are exempted from a prohibition on parades and pickets, the rationale for regulation is fatally impeached.” See also Police Department of Chicago v. Mosley, 408 U. S., at 100; Village of Schaumburg v. Citizens for a Better Environment, 444 U. S. 620, 638-639 (1980).
See generally 29 U. S. C. § 141 et seq,; Thornhill v. Alabama, 310 U. S. 88 (1940); AFL v. Swing, 312 U. S. 321 (1941). Appellant does not go so far as to suggest that the National Labor Relations Act preempts the State from enacting a law prohibiting the picketing of residences involved in labor disputes. Such an argument has dubious merit. See Machinists v. Wisconsin Employment Relations Comm’n, 427 U. S. 132, 136, and n. 2 (1976).
See Ill. Rev. Stat., ch. 48, § 2a (1977), which provides:
“No restraining order or injunction shall be granted by any court of this State ... in any case involving or growing out of a dispute concerning terms or conditions of employment, enjoining or restraining any person or persons, either singly or in concert, . . . from peaceably and without threats or intimidation being upon any public street, or thoroughfare or highway for the purpose of obtaining or communicating information, or to peaceably and without threats or intimidation persuade any person or persons to work or to abstain from working, or to employ or to peaceably and without threats or intimidation cease to employ any party to a labor dispute, or to recommend, advise, or persuade others so to do.”
We note that the statute’s labor dispute exemption is overbroad in this respect, for it not only protects the rights of the employee to picket the residence of his employer, but it also permits third parties to picket both the employer and his employee, even when there is no dispute between those individuals. As appellant’s counsel explained at oral argument: “[T]he labor dispute could exist even if the employee wasn’t part of the dispute. For example, if you have a condominium that employs non-union janitors and the non-union janitor is perfectly happy to be there, conceivably union janitors could engage in picketing, very much like a traditional labor law cane.” Tr. of Oral Arg. 14.
An alternative justification for the statute — one not pressed by appellant — is that it is intended to protect privacy in the home, but only insofar as that objective can be accomplished without prohibiting those forms of speech that are peculiarly appropriate to residential neighborhoods and cannot effectively be exercised elsewhere. Since labor picketing arising out of disputes occurring in residential neighborhoods can only be carried out in those neighborhoods, the argument would continue, it is permitted under the statute while other forms of picketing, for which suitable alternative forums will generally exist, are barred.
Even assuming that a content-based distinction might in some cases be permissible on these grounds, but see Schneider v. State, 308 U. S. 147, 163 (1939) (“one is not to have the exercise of his liberty of expression in appropriate places abridged on the plea that it may be exercised in some other place”), this is not such a case because the Illinois statute is seriously underinclusive in this respect. It singles out for special protection only one of the many sorts of picketing which must be carried out in residential neighborhoods or not at all. Protests arising out of landlord-tenant relationships, zoning disputes, and historic preservation issues are just some of the many demonstrations that bear a direct relation to residential neighborhoods. See generally Comment, Picketers at the Doorstep, 9 Harv. Civ. Rights-Civ. Lib. L. Rev. 95, 101-102, 106 (1974). Indeed, appellees themselves assert that they want to engage in residential picketing because it is the only effective means they have of communicating their concern about the issue of busing to the desired neighborhood audience. Yet the Illinois statute bars all of these groups from picketing in residential areas while those wishing to picket at the site of a labor dispute are permitted to do so.

Mr. Justice Goldberg’s opinion for the Court in the first Cox case stated: “The rights of free speech and assembly, while fundamental in our democratic society, still do not mean that everyone with opinions or beliefs to express may address a group at any public place and at any time. The constitutional guarantee of liberty implies the existence of an organized society maintaining public order, without which liberty itself would be lost in the excesses of anarchy.” 379 U. S., at 554.
