Like it or not there are genetic differences between races, differences that are believed to be a product of the environment in which the race or ethnicity evolved. Take Ashkenazi Jews for example, highly intelligent and winners of Nobel prizes way out of proportion to their numbers, but also plagued by several genetic diseases …. Tay Sachs, Gaucher, Cystic Fibrosis, etc. Why? Complicated, but almost certainly a product of Eastern European discrimination following migration during the Middle Ages. Other races and ethnicities have their own intrinsic gifts and shortcomings, also a product of environment, but I think I have said enough.
