Why is it more common to see black male/white female couples than white male/black female on TV?

I knew my post was going to catch hell but I don’t have my head in the sand like a lot of you do. Too many blacks in this country were and still are following the wrong role models. I don’t care what race you are if you don’t do your best to fit into the main stream your chances of success will be lower. Nothing to do with racism everything to do with being an isolated society within a society.
