EDIT: no, I don't sympathize with nazis (neither I sympathize with those who call everyone nazi when they're losing an argument ;)
No offense but this is kind of what happens in real life too. Nazi shows up to local bar. Barman or owner doesn't throw them out. Eventually they invite their friends. It winds up being known a Nazi bar. People who don't want to associate with Nazis no longer visit the bar. This is why intolerance of the intolerant is a thing.
