Baynard Rustin who was also one of MLK's strategists was, in addition to being brilliant, blantantly homosexual. Back during the civil rights movement this was, of course, frowned upon. King, himself, was a notorious womanizer. In the Aretha Franklin bio I just recently read it told how her father Reverend C.L. Franklin a prominent Baptist preacher, civil rights crusader and confidant of MLK was screwing half the women in his congregation.
The Black Panthers were very chauvinistic, relegating women to subservient roles. Kathleen Cleaver, wife of Panther leader Eldrige Cleaver, finally left him because she got tired of him beating her up. Angela Davis and other female activists also complained about how male -dominated these militant movements were, never allowing women leadership roles. These "black is beautiful" sloganeers also displayed appetites for white women.
The Black Muslims banned women from their hierarchy, too, expecting their spouses to obey and serve their husbands to the point of allowing them to practice polygamy. Boxer, Muhammad Ali, took on another "wife", while still married to his first one.
"Boys will be boys", and their vices transcend race. Religion has never interfered with sexual debauchery, either. All the biblical patriarchs were playas.
