To be more precise, HB may be be “sociologically Black”, but she almost certainly has more European ancestry than African*. If we went by majority ancestry, HB would be White, not Black. But in the US today, we typically assign race to someone by however they identify themselves. HB calls herself “Back”, so she’s Black. She could just as easily, perhaps more accurately, describe herself as White (assuming she had to choose only one standard racial description). The guy in the OP’s picture might be of the same situation.
I’m not disagreeing with you, Blake, just stating the case in a slightly different way.
*Her mother is White/European, and her father is Black/African, but it’s exceeding rare for any African-American to have no European ancestry at all.
There was a real black albino at the college I went to. White skin, but otherwise had all the traits associated with American blacks. Culturally, there was no mistaking that he was black; he wore urban-style clothing, spoke in African-American vernacular English in an African-American accent, socialized mostly with blacks, and involved with the Black Student Union; I’d see him manning their booths.
I knew a pair of black brothers (literal brothers, as in same parents) in my neighborhood in college. Except for the fact they were completely white, those guys were completely black.
I lived in a rural region of Jamaica where there happened to be a number of albinos. Their facial features were the same - or, more accurately, varied as facial features do in all individuals as in the rest of the African ancestored population. They did tend to have terrible problems with their sensitive eyes, as the sun is strong there and sunglasses aren’t typically worn. They also had a lot of skin problems - lesions, freckles, peeling, etc. - because sunscreen isn’t used much there and people don’t realize, I guess, that albino people need protection from the sun for their skin. Jamaican’s have nicknames for everybody and tend to call all albinos “Yellowman” or “Yellowlady” which is why the albino reggae star took that name.
