This is correct, and also, Nazis don't care about good faith argumentation. They're explicitly anti-liberal (as in, liberty, freedom) and will only pretend to have these values to try and point out an apparent contradiction ("You believe in rights to speech and democracy, so why are you censoring us?")

In this video of former white supremacists talking about how they left the ideology, one brings up that on their Nazi website, it was normal and common to argue for points they knew were garbage, like the Great Replacement theory. It's about power and results, not liberalist idealism.

Violent methods usually aren't the preferred way of dealing with Nazis (because it's harder to get a mass movement to join in and support it, and because it's riskier, legally, which makes it harder to sustain), but it works. It broke up the BUF in Britain, it's kept the local turds scared to show their faces or reveal their true thoughts (don't worry, they still usually get revealed by researchers anyway). Violence works. They know it and we know it. But when they're the government, their violence is now legal.

History has proven this.

The violence came from outside the country last time. That's not happening this time.
