No, he couldn't, because for Reddit atheists to condemn Nazis they have to go through a ritual where they talk about Jews being awful and how it'd be better if they didn't exist since organized religion is evil.

>there are other places where it would be much more appropriate to do so.

Ah, yes, polite society requires antisemitism be done in the appropriate places.

Knee jerk reactions? Jews asked to color in a little menorah and for people to put it in their windows for solidarity and you went into convulsions bitching about Jews.

>I'm not even going to debate the merit of using the term genocidal

You can't justify your using the term, because it's just a lie.

I'm a Jewish man and don't know a single Jewish person who would say something as batshit weird as that. You're probably not even Jewish.
