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.
Yeah it would be hilarious to any scot or welshmen trying to lump them with the english.
But the welsh were one of the first people from Britain along with the english to emigrate to America.
So often these people venerate them, not quite as much as they love the english, but they definitely venerate the welsh as part of the "old stock"
