I think this comment is pretty unfair. You're right that there's a historical demonization of Jews that continues to this day, but i don't think it makes sense to suggest that the only solution is for all the Jews to hide out in Israel (or some other Jewish nation/state).

That said i don't think it makes sense to say they have to leave for that reason either, or that it's the smart thing to do or whatever. Why not stay? If only there were more secular Jews in Israel who opposed apartheid.
