Skin colour should make no difference whatsoever, it is all down to how people conduct themselves. If a person demands something because they are white, then that is wrong, equally if a person demands something because they are Black then that is also wrong.
What lets some Black people down is when they constantly bring up the subject of slavery . This happend many many years ago, yes it was atrocious but now is the time to move on.
In fact in some ways it did some good, especially to the slaves decendants, because they are now much better off than if they had been born in Africa, and I don't think there are now many that have any wish to return to their roots in Africa.
