I have no idea. I guess it's because they can get away with it, but I think it's really interesting that you bring up the fact it's only American blacks. My aunt's from Nigeria and she says the same thing.
Personally I'm sick of all this racism. Why can't people just except the fact that everyone is different. Who cares if someone African American, White, Hispanic, Asian, or any other race.
We are all equally as important and should not be judged by the color of our skins.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
