not sure why anyone thinks this is a racist thing.don't know about the muscle mass thing but african americans don't swim in the same numbers as caucasians. I coached swimming on and off for 30 years. i have taught lessons for all ages. Asians are the fastest growing group in competitive swimming. I also dont know why this is important in any wayFYI, I taught swimming for two years in high school to mostly African Americans so I can attest that some of them can swim. They do have a slightly higher muscle density than Caucasians which makes them tend to sink instead of float. This is the worst LAMP post ever.
