People erroneously equate skin color with "blackness". There's really no true measure of "inherent blackness" and like you said it's a social construct. I'll probably catch flack for this but I believe Rachel Dolezal is black.
There are genetic studies that show that a African Americans in the U.S. are genetically more related to white Americans than many ethnic groups in Africa, especially eastern Africans e.g.. eritreans, ethiopians.
Dolazea made a good point, everyone is from Africa so technically speaking she's black...but of course that's a little bit of a stretch but I get it.
It's a double edged sword, this oversimplification of African culture can be harmful, but from a unity standpoint I can see how it is beneficial.
One of my Asian friend's from Queens raps and grew up around nothing but black people. If we are using hip hop culture as a measure for blackness, he is very much "black" by that standard. At the end of the day he knows he isn't black. He says the N word tho but it sounds genuine coming from him cause he doesn't overuse it. I've met Asians from places like cali who literally use it every other sentence and have never hung out with a black person in their lives.
I am sure when the doors are closed behind them, they talk about them as "those people." So yea man, not buying the whole inclusion thing in the whole power structure.
