methinks he's talking about the scientific definition of "race" vs its common usage.
You can have light skinned African american who has whiter skin then some white guy (for example an olive skinned Italian). That doesn't make the African American guy "white".
Okay, it goes like this; some point in the 16th or 17th century whilst everyone's out there busily cataloging the natural world, someone has the great idea of doing the same with people. So they choose skin colour 'cos it's kind of an obvious thing, and decide that people with a different skin colour must be a separate subspecies. Some people figured there was as many as 300 different sub-species, but most commonly it was three to five, with white people at the top, because they had intelligence and technology going for them which was obviously linked to their whiteness

, and black people at the bottom, because with their black skins and living in the jungle they were obviously barely above animals. Orientals floated somewhere inbetween; not quite as good as whites, but obviously tons cleverer than blacks.
A couple of people named deGobineau and Chamberlain are worth mentioning here, as their "research" into race had a profound influence on a certain Mr Hitler. Anyway, these days, race and ethnicity are used kind of interchangeably, but some people are still clinging on to the old racial classification even though research shows there's no evidence for it at the genetic level. people have different colour skin--so what? If someone could figure out a way to safely boost your melanin levels, you could be as dark as you want to be; basically, using skin colour to classify people is as useful as using eyecolour or height. So skin colour is biological, but race is cultural; you're
born into a culture, but you aint born
with culture, unless anyone wants to throw out a claim for culture and language being encoded at the genetic level?
