Imagine being so retarded that you think race is all about pigmentation. Or even worse, imagine being that retarded that you know it isn't, you know that race is in everything from pigmentation to bone structure, density, musculature, hormone system, blood antigens, digesting system, but you still think that evolution left cognitive capacity out of the loop somehow.

Genetics is potential. Caucasians have a higher potential for intelligence than Negroids, Mongoloids have a higher potential than whites. Not everyone lives up to their potential, hence white trash exist (and so does Asian trash), but this will not change the fact of genetic divergence just to induce fuzzy, warm feelings in retards like you.
