Gmy, I would totally believe that most Americans see biracial people as black if it wasn't for folks like Tiger woods. The man looks more black than Gates. Yet that doesn't stop him and others from rejecting the label. Did we mention that he was beating up as a very young child and called a monkey? His father didn't want him to have anything to do with his AA side it seems. He coined the pharse Cablinasian .In the past America was big on the one drop rule but there were still people like Tiger woods. Why do you think the black American population stayed at 12 percent for so many years? Many biracial Americans pass over into hispanic or white. Like that author from the New york times.

The UK is a bit different. Most mixed race people live with a white parent,and some only think about the white side because thats what they grew up with. You have some who travel abroad to other European countries and they don't know how to deal with the black experience when its in their face. What they fail to realise is mixed race people who are half Asian half white don't get the same racism. The black popultions in caribbean has more history,or a better understanding than those in the UK.
