Communism should be outlawed alongside Nazism.
Damn commie filth praising despotic murderers and complicit in the downfall of Western civilization.
Ideas (thoughts) can't be outlawed. At least not in a free country.
Thought crimes aren't crimes.
That doesn't mean that there can't be laws against incitement and the like, but simply reading subversive words can't be outlawed, except in a totalitarian State...
