There are statics somewhere that had some 20%+ of people who are looked at as "white" in the US actually have recent African ancestors as well. The Irish and Italians had to fight to be called "white" in the US because in the US being "white" meant being at the top of the class hierarchy. Which is all the race thing is, class hierarchy, and why no one can actually define a taxonomy for it because it's based on the arbitrary.
