Several activists and scholars have criticized the practice of limiting hate speech. Civil liberties activist Nadine Strossen says that, while efforts to censor hate speech have the goal of protecting the most vulnerable, they are ineffective and may have the opposite effect: disadvantaged and ethnic minorities being charged with violating laws against hate speech. Kim Holmes, Vice President of the conservative Heritage Foundation and a critic of hate speech theory, has argued that it "assumes bad faith on the part of people regardless of their stated intentions" and that it "obliterates the ethical responsibility of the individual". Rebecca Ruth Gould, a professor of Islamic and Comparative Literature at the University of Birmingham, argues that laws against hate speech constitute viewpoint discrimination (prohibited by First Amendment jurisprudence in the United States) as the legal system punishes some viewpoints but not others, however other scholars such as Gideon Elford argue that this may not necessarily be the case. John Bennett argues that restricting hate speech relies on questionable conceptual and empirical foundations and is reminiscent of efforts by totalitarian regimes to control the thoughts of their citizens.
