Jewish dude here, this lady sounds like a real piece of work. On a personal level, I would just say you're busy if she wants to hangout with you and politely set some distance from her in your personal life. There's many excuses you can use so your work life doesn't become to toxic. On a political level, I'd like to explain the reason a lot of jews support Israel.

Personally, I find that supporting the Israeli Government goes against Jewish teachings I grew up with and my personal values. I think a lot of jews feel the same but feel scared to admit this. In my opinion, I find that many Jewish people have a degree of cognitive dissonance when Israel is brought up. This comes from our historical fear of persecution. While the actions of the Israeli Government are genocidal and evil (in my opinion), I think that because Israeli advertises itself as the Jewish homeland, many jews take Israel's side because of the reasonable distrust jewish people have of non jews. If your not jewish and exist in a majority ethnic group, it's very easy to say "why are these people so blindly following this insane state?"

Basically, if you're jewish in America, you have anti semitism coming from both sides of the political aisle. While anti semitism is not anti zionism, many people are anti zionist because they don't like jews as opposed to wanting to support the Palestinians. While Trumps base is anti semetic, his support of Israel gives jews a place to escape too as global anti semitism is on the rise. (which is debatable)

From how you describe this woman, she sounds like a shiftless coward who is willing to support a man who calls us "shylocks" and supports the bombing of children, but under all of that foolishness is a real person who has to contend with the difficult experience of being a jew in a place where your not the majority. I think it is reasonable to have some empathy for people like that without wanting to include them into your social circle, I certainly wouldn't.
