I don’t think it would do anything. As a matter,of fact, they’d probably see more European than they expect and get pissed off and call DNA tests racist. I’m surprised they haven’t done this yet...saying the database geared toward People with euro blood. It’s kind of funny how they like to say that white people have no culture, our food sucks and we are boring/generic etc. I am Italian American living in the nyc area, I have friends from here who are polish, Russian etc who are still here because their families came here like mine did through Ellis Island and we all have strong identities related to our backgrounds and they are all different. I still cook foods my relatives taught me , I don’t really cook stereotypical “American” food and there are cultural habits I have too. No white bread or mayo in my life yet that’s what they toss at you as an insult. Realistically they have had far more of that than me. Culturally I am not a blank slate ‘Merican. Same with my friends. One goes to her Ukrainian social club and the other hangs out with Her polish Eastern Europe Group of friends and they don’t speak English when together. I don’t think American blacks have these sort of subgroups. The blacks who do have cultural identity are not American blacks.
