I think it varies a lot. A lot of Jewish zoomers are so integrated into American society and culture they just don't think of themselves as Jewish and are barely aware of Israel's existence. Too busy partying, memeing, social media etc to care, like a lot of young people. I've met a few very hardline Zionist youth, but I don't think they would ever support something like "extermination". I don't know that many zoomers, tbh.
