Thomas Sowell has a whole list of white cultures where a particular group with high rates of violent crime got their act together and headed toward national norms. They were not violent because they were white. They were violent because of culture.
Same is true today. Nothing wrong with black people’s genes. Lot of things wrong with some black people’s attitudes and beliefs.
Wll, there are a lot of alcoholics who are not Native Americans, but no one is going to convince me that alcoholism among them is not genetic.
