Malcolm X said this quote

Thoughtful white people know they are inferior to black people. Anyone who has studied the genetic phase of biology knows that white is considered recessive and black is considered dominant. When you want strong coffee, you ask for black coffee. If you want it light, you want it weak, integrated with white milk. Just like these Negroes who weaken themselves and their race by this integrating and intermixing with whites. If you want bread with no nutritional value, you ask for white bread. All the good that was in it has been bleached out of it, and it will constipate you. If you want pure flour, you ask for dark flour, whole-wheat flour. If you want pure sugar, you want dark sugar.
