At one point I would have agreed 100% with you, but I think throughout history there's always been a tension whereby tolerant and democratic societies somewhat repress speech that's antithetical to their existence. Imho, this is a good thing. Some ideas are too virulent to be fought fairly and will dominate without work in the shadows to resist them. Aka "if you eschew a strictly dominating strategy for moral reasons, and your opponent doesn't, they will win." So I think there's certainly a back and forth. Neo-Nazi's (or Democrats, or Republicans) shouldn't be allowed to visit public grade schools and indoctrinate children, but they do deserve free speech.
