with the bizarre notion that Israel-born Israelis can just be shipped back to where their ancestors came from in Europe

The majority of Israeli Jews are Mizrahi who came from Middle Eastern countries. They are also the political base of Likud and other right wingers. Itamar Ben Gvir is an Iraqi Jew for example. The Ashkenazi (European) Jews are more likely to be center and left.

Of course Western activists don't know any of that. For them Israelis = white = European = evil, Palestinians = brown = good is the only model to understand the world. Palestinians and Jewish Israelis are indistinguishable just from looks. Both have pretty varied phenotypes from blond to black.
