I’ve already seen it. I think the common term is “self-hating Jew”.

“anti-Semitism” used to be a term with a lot of weight and serious connotations. Now, it’s been misused and abused so often that the power it once had is gone.

If anyone who disagrees with the genocidal far right government of Israel is an anti-semite then, of course, the term will lose it’s power to shame actual bigots. It should surprise nobody that actual anti-jewish bigots are coming out of the shadows.
