Late response on my part, but it sounds like we're mostly in agreement.
I will add that I think what people would accept is different from what they will tell interviewers they want.
I agree that there will be antisemitism everywhere, and as a Jewish person doing organizing work with Jewish groups, there will certainly selection/sampling bias among the Palestinians I interact with.
I'll also say that the prejudice of the oppressed shouldn't be seen the same as the prejudice of the oppressor.
If a slave in the U.S. in 1840 believed white people were inherently incapable of empathy, I imagine that the only people focusing on their "anti-white racism" would be doing so to defend the status quo of slavery.
When Palestinians living under occupation talk about "Jews" it's likely that the only interactions they've had with Jewish people were with IDF soldiers enforcing their occupation, perhaps shooting at them during peaceful protests, killing their friends, their family members, and so on.
The focus should be on liberation, even if people with problematic beliefs are among the oppressed.
Even if it's the case that most people in Gaza and/or in the West Bank are antisemitic (and even if it was the case that most of them "wanted all Jews dead", which I think is a gross mischaracterization of the situation) that doesn't mean they would turn down a justice-oriented plan which would allow them to participate with full equality under the political systems that dictates their freedoms.
I understand the circumstances that lead Palestinians to be antisemitic. That said fair, the person you responded to said this:
> the entirety of the surrounding populations want them dead
I admit that it's a ridiculously hyperbolic comment, but most of Israel's surrounding countries do have an environment that's extremely inhospitable to jews and that can't really be attributed to Israel oppressing them all. They were ethnically cleansed from nearly every other country in the middle east - I think that just as we can understand why Palestinians ended up antisemitic, we can understand why jews in Israel ended up being uncomfortable with the idea of Israel not being an explicitly jewish state. Two wrongs don't make a right, but to make any progress towards a single state solution with equal rights for everyone, Israelis will need to be convinced that it won't result in a "two wolves and a sheep voting on dinner" situation.
