There is not one caucasian person in the top 10 fastest 100m sprinters (http://www.toptens.com/sports-track-sprinters/). Do you believe that this is somehow problematic?
Genes and gene expression affect neurotransmitter levels and neurotrophic factors which, in turn, affect cognitive performance - just as Jamaicans and Africans are on average better at sprinting than English and French natives. Particular genetic groupings are going to fare better at task X, not too badly at task Y and terribly at task Z.
This is not privilege, it is reality.

As to my post, what I would say is that you and I are having a productive conversation in part neither of us is labelling the other as overreacting. Instead, we're trading viewpoints and questions.
Another example:
> Different studies have found different results, but most have found above-average verbal and mathematical intelligence in Ashkenazi Jews, along with below-average spatial intelligence. Some studies have found IQ scores amongst Ashkenazi Jews to be a fifth to one full standard deviation above average in mathematical and verbal tests.
