I don't think it has much to do with fairness. Africa has fair&lovely too. But from what I hear they love black people. (Never visited myself.)

It's the particular distaste for Africans that I don't understand. All foreigners face a degree of racism, but Africans seem to get it the worst. Women tend to be the most racist, morality police and spurned vixen depending on the situation. If an African woman wears shorts in her housing society it's a danger to good morals. And if an Indian woman tries to pick me up but I don't feel like dumping my (Mozambican) girlfriend right there, somehow the black girl is the problem.
