The mainstream accepted view on human population differences is so schizoid to me. On the one hand, you're supposed to believe that "race is a social construct", and indeed many aspects of race/ethnicity are arbitrary and socially constructed.
On the other hand, it's well documented and widely accepted that huge number of measurable and physical traits including skin color, eye color, hair color, hair consistency, face shape, height potential, facial hair growth, and susceptibility to both genetic and infectious diseases (see for example, Cystic Fibrosis and Northern Europeans, Sickle-Cell anemia and Sub-Saharan Africans), are strongly correlated with race and ancestry.
But you're supposed to believe that the same genetic variation that causes all of these physical differences between groups has no effect at all on behavioral differences. Personally, I don't understand how one can honestly reconcile that. I understand why it's not discussed in the current milieu, and I understand that it's potentially very dangerous to the existing social order, but as far as I'm concerned it's a pretty obvious thing to anyone who is willing to see it.
