Well I can tell you from day-to-day experience in Germany that the fact it’s illegal to say „Heil Hitler“ and similar nazi slogans draws a very clear line between ordinary citizens and right extremists. It’s a good thing nobody can walk around and loudly proclaim their veneration for the darkest period in our history, for doing so makes them an enemy of our democracy and everything it stands for. A society has to have limits to the tolerable, and defend them.

This has worked well for more than half a century here, and I assure you that Germany hasn’t succumbed to a totalitarian regime yet. Quite the opposite to some, erm, land of the free that seems to struggle a lot with freedom lately.
