Haaretz, the Israeli newspaper, is the source of that poll. Here’s the original link to the article that discusses it (it’s paywalled, which is probably why it’s so hard to find).

The poll was conducted in May, so the numbers have probably changed a bit, but I totally understand your skepticism. Unfortunately, as an American Jew who is the grandchild of Holocaust survivors, I’ve spent a lot of time in Israel, have Israeli family, and I have no trouble believing these numbers. It’s difficult not to generalize, but based on my personal experiences with my family, as well as talking with Israeli Jews, Israeli Arabs, and Palestinians who live in the occupied territories, there is disgusting widespread hatred against Palestinians and Muslims in general that has been completely normalized across Israeli society. It’s by no means every single person, there are still loads of lefty anti-establishment and anti-Zionist movements, but I have no trouble saying that the majority of Israelis hold abhorrent views about Palestinians. It’s definitely not antisemitic to describe the hatred I’ve witnessed coming from Jews against Palestinians. I can’t even count the number of horrendous things I’ve seen.

Racial slurs are the norm, racial profiling is legal and expected at the entry to every public business, segregation is expected and accepted, Jewish children are taught to hate Palestinians, and every Israeli (with some exceptions) is conscripted into the military, so they are all indoctrinated into a system of state violence.

The person you were responding to seems to think that murder is acceptable in service of a just cause, and I couldn’t disagree more. Murder and violence are never justified, even against those committing them.
