My best friend is very pretty and she looks perfectly white because she is a South American that if she didn't come to you and tell you, you wouldn't understand it yourself. If she invited you to one of her birthdays, her parents would be there, and there I could see that both of her parents are specimens of a very proud and obvious unequivocally black race.
And she herself, when she talks to you, is proud of her origins and often complains that she left South America as a child and there is not a single book or documentary of any kind about her Country of Origin, which is Equador. People of all races are spontaneously drawn, on a conscious or unconscious level, to their main race of origin. You cannot change that by hoping to deny it and make her do the same.
Would you willingly go into the life of Africans according to their customs and traditions to feel yourself one of them fully? No. You wouldn't. I myself love the Black Race because it fascinates me so much for several reasons. And for that very reason I care about keeping it alive in its identity. So that I can watch as it evolves and manifests itself more and more interesting and surprising me all the time.
