> Laws against speech do not change minds,   Are you saying that speech laws don't have any influence in what people see and hear? Or are you saying the information people get has no influence over their views? Either is absurd.     Just as important as outright bans on particular viewpoints are control over the mass media, the academia and education system. Censorship works, propaganda works and mandatory viewpoints work.   They do actually. How do you think Europe was Christianized? It was by decree. Peganism and blasphemy was criminalised, and if you were expelled from the Church you lost the protection of the law.   >they only enhance resentment and increase radicalization, driving subversive movements underground.   Those are symptoms of repression working not being futile. Movements have a much harder time recruiting when they're underground. And maybe at some point the movement you've suppressed will be completely dead.   >Speech must be free in all public and common areas, the government cannot be allowed to restrict speech. Only on private property can speech be restricted and there the only acceptable method of enforcement is to eject the violator from the property.  It's pretty retarded to accept tyranny under the guise of private property. Social media is the most important forum of public discourse today and completely controlled by private actors. At least the government has a constitution to follow.
