“anti-Semite” has become as shopworn an accusation as “racist”. Whenever either term is thrown about it should be totally ignored, because it’s just being used to stifle free speech.
It is true that once garden variety racists get established on a forum, it isn’t long before the hardcore Nazis show up.
Sorry, but there are real antisemitic attacks, and there are real antisemites like Nick Fuentes. The fact that the Left misuses a term for politics, doesn’t mean it isn’t an issue.
