Listen to the young Cassius Clay (or was he Muhammad Ali by then?) in 1971, speaking on the necessity for marrying within one’s own race. He is witty, intelligent, articulate, and absolutely politically incorrect, even by the standards of his time.
Watch the discomfiture of the BBC interviewer, as if he is thinking: This man is an authentic Afro-American — how can he say such dreadful things?
