Much of this is because some, and I stress SOME black people keep making it into on.
I recall in the UK a few years ago, it was a statistical fact more black youths committed crimes on the street, and a high ranking police officer said this and was slaughtered for being racist and suggesting black people are criminals, when he was only relaying the facts.
I don't care what nationality, colour, sex etc you are. There are good and bad people in every single culture and country in this world, everyone is an individual, but even I'm sick or some black people twisting things into being racist every time they don't like something.
