Is It an Interesting Social Choice to Call Yourself Black or White?

Where's the bright line between a white person and a black person in America? There may not be one, rightan my gor brooker has over 50 % european ancestry. And it seems to me to be a deeply uninterestinga and probably political, toxic project to try to give a genetic answer to the question self identity. I mean, these groups are fungibe. People are fungible. We will continue to change and mix. So the idea that we can just like, take a frieze frame of how people look to day in groups that we've been calling white, black, asian is a very vague term.
