Itl go round in circles forever, because the second you point out there is a diffirence in skin colour, you point out the fact races will never be identical. As soon as that happens, you have differences that are measured.
Just like how people are judged for being too fat or too thin. Unless we are all identical, human nature seems to dictate we will always argue over our differences. I'm a firm believer in the fact itl never go away.
