Another useful idiot chimes in.

Debate is a battlefield. To deny it is to cede it. The bad speech becomes samizdat, the bad action continues, and no one gets to see it opposed, because there is nothing to oppose. How are you going to condemn a fascist for saying things you don't let him say?

Curbing speech is Bolshevik nonsense. Shame on you, Prof. Palumbo-Liu.
