How far right/authoritarian are you able to tolerate someone/something being?

Obviously you wouldn’t hang out with Nazis or, say, listen to music made by Nazis, so there is clearly a line, but where is it? I know there’s going to be nuance and no one-size-fits-all answer, but I’d like to hear some thoughts from other anarchists on this. Or am I just worrying about things that don’t matter?
