This should would explain the propoganda, virtually every advertisement, music video now pays white traitors to act like they are in love with every black guy they see.
mostly, women have sex because they are lovingly or not so lovingly co-erced. black men are very co-ercive.

In other words: the same reasons men have sex. And men aren't the only sexual conquistadors: Women enjoy the thrill of the chase and can be just as viciously competitive with same-sex rivals. And, speaking of competition, the book posits a theory of "mate copying," in which women are drawn to men who come pre-approved by other women. (Indeed, who hasn't experienced a sudden tingle of attraction upon seeing another woman go after a man who was previously uninteresting?)
