Oh, that he literally believed that? I'd always focused on the metaphorical meaning of all whites are devils. I would think that if he'd literally believed that white people are devils, he would've said something about it when talking to Alex Haley.

But so far as I can tell, he did believe all white people were evil. He wouldn't have had a reason to apologize otherwise. One of the most dishonest things Spike Lee did in the movie was to only tell the first half of the story of the white girl who asked if she could help and who cried when he told her she could not.
