From a previous post:
"A note: not all Black Americans are of African descent."

This seems unlikely, as every human that walks the Earth is of African descent. No hominids sprung up any where else. We are all Africans. All else is presumption and vanity.

Possibly what the previous post meant was that, anthropological particulars aside, not all black Americans are or consider themselves to be African-American. One of my college friends was born in the Caribbean and was a naturalized citizen. She did not consider herself African-American even though she was clearly of African descent because she did not have an African-American cultural or familial legacy.

Personally, I find it obnoxious when whites (and I'm white) trot out the "we're all African" line. Our distant--very distant--heritage does not necessarily affect our life experiences. Very light-skinned black people often face less discrimination than darker ones, especially if they do not "look" black. Yes, we're all African at some point millions of years ago, but most of us haven't gone through the problems associated with being visibly African.

DNA does not dictate mindset so there would be no point in discussing presence alone of African heritage as related to how people view things. I was under the impression that this thread was started as a discussion based on cultural and experiential influences rather than anthropology.
