Of course racism, like almost anything else, is a matter of degree.
What is wrong with what is going on currently sounds as though it came out
of the Confederate States of America:
one drop of negro blood and the person is not white
So if I say to you, "Oh, you look extremely funny because you have hair like Canaan Banana (at last I have found
the place to use that man's wonderful name)."
I am a racist.
But if I say, "Oh, you look extremely funny because you have hair like Margaret Thatcher (who poor woman, was not gifted
with such a super name as Canaan Banana)."
That's OK.
Peter Ustinov had an Ethiopian lady in his family tree: an awful pity he is dead; it would be
wonderful to hear what he had to say on this matter.
