Calls to violence are not protected speech. Nazis and the KKK, while they might not quite make calls to violence, know how to word-smith the hatred and grow it, like a verbal "I'm not touching you" kind of thing. They'll make ambiguous statements like claiming they need to deal with the $SLUR problem in the neighborhood.
