I was talking about applying to the notion of raciation applied to humans. 
Humans are a species, not a race.

The concept of race is based on the notion that one can order humanity's 
genetic diversity. But this subdivision into "races" only takes into account 
a small aspect of mankind's genetic diversity. For instance, the genetic 
distance between two french populations is on average inferior only by 15 % 
to the genetic distance between two population taken at random in the world.
the racial classifications that some people used ( are they still used in 
the US btw ? I've always found that rather shocking for a country which has 
invented political correctness) are not valid, unworkable and arbitrary.

The concept of a "caucasian" race makes no more sense than a "red-haired" 
race, and in many ways each human, a unique combination of genes, is a self 
contained "race".
