Constantly. Usually it takes the form of purity tests.

• “You’re either with me or against me / You’re either part of the solution or part of the problem”
• “If you don’t satisfy all of my impossible requirements, you’re as bad as a nazi”
• "We only agree on 99 out of 100 things, so clearly you’re not to be trusted"
• etc

There are thick, uncrossable lines, and there are a lot of people who don’t mind crossing them. You cannot compromise with a bigot. You cannot find common ground with a person who would subjugate you, or someone who sees you as less than human.

We can have disagreements about many political issues, but when you are standing next to pedophiles, rapists, fascists, and bigots, you shouldn’t be surprised to be called a Nazi.

You cannot compromise with a bigot

To reiterate the comment you’re responding to, you’re reducing a complex world to a binary choice. Everyone that has ever existed is bigoted to some degree, therefore no compromise is possible ever?

Their example of bigots was racists and nazis plus pedos (which isn’t bigotry but universally frowned upon). They did NOT say, “any and all bigots, even of minor things”.

Why are you trying to make them say something they did not say?

You are part of the problem. When someone says, “I like pancakes”, what they SPECIFICALLY DID NOT SAY is, “I hate waffles”.

Similarly, when someone says, “you cannot compromize with nazis and bigots”, what they DID NOT say was, “any concervative deserves the death penalty”. Why do you read it as such?
