Black people physically dominate?

I don't buy it at all. Clearly they are overrepresented in certain sports but that is because they have limited opportunities and frankly, the doing well in regular school subjects is often considered acting white. More of them are willing to risk injury and brain damage. I got hit in the head in high school by a former marine and that was enough for me. It just isn't worth the risk to me to have my brains scrambled. The four years I was in the Army where strength really gets tested, there was certainly no physical superiority noticed by me there.
