Dudes claiming they are "old stock" or "heritage" Americans. They'll even call other white people who's ancestors weren't here before the Civil War "ellis islanders" and invaders.
As someone who's ancestry has partially been here since the 1690s.. it's a crock of shit and silly as fuck.
White supremacy can always be mocked because for lack of a better term, their “final boss” isn’t China, or the entire global south ready to take revenge, it’s always some form of “lesser” whites, usually “da jooz” will do, but anti Eastern-European sentiment and antisemitism usually go hand-in-hand.
And even then, white supremacists in the west seem to be willing to play nice with Duginists for now, so I could be wrong.
