A lot of Jews have become completely unhinged since Oct 7th. I think most Jews actually hate the anti Israel left more than any group of whites on earth, including the alt right. To them some bleeding heart shitlibs like Jeremy Corbyn or Roger Waters are a way bigger threat than some 4chan trolls, solely because they criticize Israel.

Back in the early 2000s when the Palestinians launched their first intifada you saw the same thing, with supposedly left wing Jews completely losing their minds, including some prominent ones that openly talked about the possibility of unleashing the Samson doctrine if the Palestinian attacks continued. One prominent journalism professor even wrote an infamous op ed in the LA Times about it. I think this was actually a lot of the motivation behind flooding Europe with Muslims, and I've come across Jews that talked about it being revenge for criticism of Israel and support for Palestine.
