You don’t need to be a Jew to support open borders and mass migration, and you don’t need to be an Anti-Semite to think open borders and mass migration are both terrible ideas.  

I don’t care at all about the whole Jew thing except that Israel hasn’t been a good investment for the American government and its people, but many Leftist Anti-Nationalists (not just Anti-Ethnonationalists) would agree that supporting Israel so heavily hasn’t been a good investment.

Of course, there’s a faction in this country that needs Israel for its end times prophecies, so we probably still won’t see the whole Palestine thing resolved in our lifetimes.
