Are you just going to overlook the part here where most of the white nationalists really hate the Jews? And the part where the Jews that wanted an Israel were not among the least competent of all Jews?
Anyhow, if it’s small and powerless enough, I don’t really care if there’s some racially-exclusionary city of 50,000 - 100,000. They get to have their little white ethnostate, the rest of us get to have them no longer included in our politics.
Maybe they’re right, and it’ll be full of great city-state statistics like Hong Kong or Singapore, only you know, ethnonationalist. Probably not, though. We’d have to intervene if they tried to bring back slavery or something.
As you may know, street fights with these people are being used as a justification from the Left to attack our rights, and the behavior of a bunch of fight-happy Communists smashing junk is being used for the same by the Right.
