Well...you get extra points for referencing the great Dr. Welsing. She was right, of course.
But there's also this: Dr. Leonard Jeffries (Hakim Jeffries' uncle) was thrown out of his university professorship because he posited that "white" people act like they act because they evolved in Ice Age Europe, and had to fight tooth-and-nail for every scrap of food, clothing and shelter. That's why they value competition over cooperation.
Others have argued that paleoanthropologists are not telling us the truth about the Neanderthals...and how much Neanderthal DNA contemporary white people have in their physical and mental makeup. They were really not much more than cannabilistic beasts, who preyed upon those black Cro-Magnons when we migrated into Europe.
