Edit: I want to preface this comment by saying that you don't seem to be conflating zionism and Jewish ethnicity/culture. My reply is more of a general comment on how people can sometimes mix these up, partially because within Israel (and especially from the perspective of a Palestinian), they have close to 100% overlap, and how it's a grave mistake to extrapolate that outside Israel where Jewish cultures exist that long predate the existence of Israel.
No one wants to name the actual problem.
Long reponse.
The actual problem is zionists. In Israel, due to the power structures in place, that's almost all Jews. Outside of Israel, you don't gain anything from tying Jews to Zionism rhetorically, that's what the zionists want. If you dig deeper into the polling, you'll see large differences by age group and financial situation among Jewish people.
I think that if someone brings up concerns of "antisemitism" in response to pro-Palestine discourse, then they should be dismissed. It's just not the case that there is any actual significant amount of antisemitism in the mainstream international pro-Palestine movement, and there literally cannot be antisemitism in Palestine, it isn't possible with the power structures at play (it's like talking about anti-white racism in America).
However, mixing the Israelis with the Jewish diaspora into one category is not only incorrect, it's an incredible own-goal that concedes to Zionists almost the entire basis for their psychotic ideology.
For some reason people on the left are ready to give Jews (not all of them) a pass for being genocide supporters simply because they're Jewish.
Liberals do this. I doubt you could find a significant percentage of actual communists who believe this.
The same cannot be said of their attitude towards other genocide supporters who are of a different race.
Liberals do this as well, sometimes, but it would also be wrong to say that e.g. Turks are inherently genocidal. Partly because it's just reactionary, and partly because it helps absolve the people who support genocide of their choice to do so. Non-zionists and anti-zionist jews exist in large numbers, and they show that the central argument of zionism is a lie. They live well outside of Israel and feel no need to commit genocide to have "their own state".
I disagree with this comparison because it's completely reasonable to expect someone to be ashamed of being American or of being Israeli, but not reasonable at all to expect someone to be ashamed of being Jewish.
There's a qualitative difference between a nationality and an ethnicity/cultural group that predates any existing state.
My main problem with BE is that he's just wrong a lot of the time, and actively and materially harmful to other people who are much better leftists than him.
