.. Because your pigmentation is not a social construct, it's determined by DNA.

I would argue that it is a social construct.  We're all a bunch of mixed half breeds that have collectively decided to ostracize and categorize each other. If you're from mostly European lineage you're white however, from certain Asian lineages your skin color looks white to the eye but you're still labeled as Asian not "white"; in other areas of Asia your skin is more brown and yet you're still labeled as Asian. It's all a social construct. 

In other thoughts: your brother from another mother should be changed to brother from another father because just about all of us came from gengis khan.
