i cant stand closet blacks or women.
Actually, believe it or not, that's not entirely unheard of. Many people have hid African ancestry in the past. Certainly there have been instances of women hiding their sex as well.
Actually, interesting story... the man who discovered DNA just had his DNA mapped. He has spent much of his career saving that there are clear markers in DNA that justify, scientifically, that blacks are inferior, genetically. So turns out that he himself has several African markers in his DNA, indicating a black great-great grandparent.
