Yes, You Do Have to Tolerate the Intolerant

Overall it is a complete inversion of historic facts that Nazis were successful because people had too many rights to express themselves. On the contrary, they gained support because people restricted speech out of fear and they could portrait themselves as victims. After they came to power they thankfully expanded on such restrictions of course.

I believe the number of totalitarian regimes that came to power because of too many freedoms regarding expression is fairly low, not to say exactly zero. But exactly none of such regimes can survive without censorship.

So the case should obviously be quite clear.
