There was this thing you all constantly choose to ignore, called the holocaust, that afaik not just a lot of antifascists see as a reason why Israel must exist
the vast majority of jewish people in eastern europe post-war didn’t migrate to either the autonomous oblast the USSR set up or Israel and chose instead to live in the eastern bloc or USSR proper, so they probably count as ‘a lot of antifascists’ that don’t see a reason for Israel’s existence
