Should freedom of speech be granted for them?

By and large I'm against censorship, but only a simple-minded fool thinks that freedom of speech should be absolute. There is danger in screaming "Fire!" in a crowded theater, and fighting words are banned because they can incite violence. So there is a difference between general hate speech and singling out individuals for hatred and intimidation (which is what PJ does to us and why that should be curtailed.) If white supremacists made a site in which they listed certain minorities by name, posted pictures and basically attempted to paint them as horrible people, they would be shut down in an instant, as they should be. But if they wanna vague threats or insults about some minority or other, than that should allowed. Hate speech that is aimed at individuals negatively affects their lives, just as slander or libel does. It is going too far.
