I disagree about the accent part for one very simple reason - there was an entertainment industry that existed within the UK, that existed purely by imitating and mocking people of different races.

Shows like "the black and white minstrel show", the stream of racist accents thrown around by comedians like Jim Davidson and Bernard Manning, and the way Hollywood would rather black face white people up than use black actors.

That's the historical (recent) context that has to be acknowledged. I also disagree with Gina's claim of racism, but funny accents of funny people was a staple in inequality in this country (and across the west) for a long long time.
