I can always separate the art from the artist. I mean, Hitler wasn't a bad painter. More like upper-middle-class, if you want to nitpick. Anyway, I think Cosby actually struck a bigger blow against race prejudice when he co-starred with Robert Culp in I Spy almost 20 years earlier. I believe it was the first American TV drama to show a white man and a black man as friends, professional partners and social equals.
