If someone compares Jews to Nazis, the group that killed half the Jews in the world, that is Nazi Inversion, and it's antisemitic. Invoking the Nazis or the Holocaust as so called "rhetorical speech" to talk about the actions of Jews is antisemitic.
It's very clear, it's very simple, and it's not stopping anyone from criticizing anything, because the same argument could be made without Nazi Inversion, and if it couldn't be, then it's not criticism at all, but simply words used to attack, intimidate or in some other way harm Jews.
I'm happy to see that other instances are starting to take Nazi Inversion seriously and act on it when their users engage in hate speech. I strongly encourage all instances who want to stop antisemitism to do the same.
