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.
1650s here on the paternal side. Ancestor was a contracted farmworker when he immigrated. The last name is fairly uncommon, which makes tracing the history easier.
