alt Hacker NewsGP is saying neo-Nazis are "not just politics, but also something worse". You're not really disagreeing with them, maybe just missing their point about some ideologies being worthy of planned exclusion from a civilized society. Aka the paradox of tolerance. That's what makes some political stances "not just politics".
I find a lot of the paradox-ness goes away when one look at such arrangements a peace-treaties. (Or at least, it gets subsumed into a broader set of respective and respectable dilemmas.)
For example, just because Country A "wants peace" doesn't mean they do nothing as Country B gets taken over by a revanchists regime declaring the treaty evil and massing troops the borders. It would be ridiculous (and depressingly realistic) for some critics to say: "They don't really want peace, or else they would be a nation of pacifists who would let themselves get annexed right now without bloodshed.)
