We wouldn't be having this conversation if they had won the war - my family would be dead and I would never have been born. Excuse me for not protecting their right to speech (which leads to action).

Nazism isn't a point of contention anymore. We know what their rhetoric leads to (because they were allowed to rise and showed the world what the consequences are). That's why I said they lost the war. It's imho a pretty strong argument to draw the line right there, to ensure the sacrifices were not made for nothing.
