Nazis are real. But it's a small group with the power of the internet. What y'all do is combine half the country with these folks.
Most Republicans aren't Nazis and don't hate black people. They are dumb dumb dumb idiots yes, but tossing them into a single identity is just shitty politics if you actually want to understand the shift right.
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.
If I see a group of racists standing around being racist. I'm not gonna evaluate every single one of them on their level of racist and excuse the guy who just likes to hang out. I'm gonna throw the entire thing away.
If there's a turd on your plate next to your dinner, do you just eat around it?
