Agree, Ippy, we've nothing like the problems that the States has.
Yes I remember talking to an American, he was a New Yorker, although I can't remember the words he used now, he had several terms of phrase he was using that I had to look up in an American slang dictionary and I can remember my thoughts of how unfair and cruel these remarks were when I realised what they actually meant.
If you can get to see or hear an unedited text or recording of the musical 'Showboat', from the twenties, not easy, it reveals more than a little about the roots of racism in the States.
Kern and his lyricist both Jews were very well qualified and able to express how things were in those days.
Both of us my wife and myself are unable to watch or read about slavery or anything like it, I can tell you it hurts like hell, and we would both be classified as white, I can't imagine how hurtful this stuff is to anyone that's on the brunt of racism whichever part of a colour chart they come from.
A stupid idea is a stupid idea and deserves any criticism it gets but what can you do about your individual ethnicity?
