The fundamental difference between black people and white people is that black people are quicker to using violence and offense and parsitoidism to spread their seeds, wheras white people first try to cooperate. Black people and white people cannot cohabitate in an area, and by cooperating, white people demote themselves the the low formica position in the polyergusformica evolutionary circuit. As such, you have to keep the black purse and white purse separated and furthermore keep the whites and blacks separated or else all you'll achieve is the "crabs in a bucket" civilization typical of Africa which continues to this day.
