The analogy comes from another post (which I can’t find at the moment) about a bartender running off a guy wearing nazi paraphernalia. When questioned by a patron the bartender explains that you can’t let them in because if you allow a Nazi in your bar once, the next time he brings a few friends. Then they become regulars and get louder and the next thing you know they have run off decent customers and you now have a Nazi bar.

Who knows if the story is true but it is meant to illustrate how fascist culture is like a cancer that takes over and displaces everything if allowed a foothold. It cannot be tolerated.

So hopefully you can see how it is not similar to having gay patrons in a bar. No one reaonably expects that a few gay patrons are going to start acting aggressively and trying to make others feel threatened or uncomfortable. But that is bread and butter for Nazis.

I was more referencing this than trying to make a standalone analogy; my bad for just assuming people had seen it before.
