jews have been banned from many places over the millennia. can they blend in with europeans? to an extent, yes. but it's not like they're indistinguishable from europeans. anyone can learn to spot a jew. these "nations within nations" could've been stopped. jews were never considered "white" (itself an american concept) until very, very recently. europeans used to understand that jews are incompatible with a european society. but ultimately, europeans chose to start treating them as equals. europeans chose to lift bans on jews entering their countries. europeans chose to go to war to stop the final solution. it's sad but it's true.
