When I said my great-great-grandmother was "unsavory," I wasn't speaking of her ethnicity but rather of her life circumstances. This thread is not just about ethnicity, and the point I responded to raised the question of people being misinformed about their ethnicity by family lore at a time when DNA testing wasn't on the table.
As to your point about Warren and her mirror, I have known several people in my generation with native or Filipino/Pacific Island bloodlines in the 25% to 50% range who could have easily passed as white, based on appearance.
I don't think it's that common, though also not rare to look white with that much "ethnic" dna.
But, this dumbass turns out to have 1/1024 Native, almost none or negligible. I have no idea where she could have bought a clue, but she and her family were wrong about being American Indian.
I try to be empathetic to Natives, genocide, land stolen, thrown onto reservations as a lasting legacy and now their very own identities being stolen as well.
That's fucked up. And it matters, American Indian lives and cultures matter. At least a little respect is long overdue.
