Perhaps these threads would die quickly if everyone weren't so inflamed about trying to stomp out a fact that has been conclusively demonstrated time and again in the research. Black men are a bit larger, on average, than white men, who are a bit larger, on average, than asian men.
If one person had simply answered "yes" to the OP, and if the entire community had simply accepted the facts as opposed to spasming all over their keyboards to stomp out the non-PC generalization, the thread would have died a week ago. It takes a lot of effort to maintain a mass delusion, which explains the eternal continuance of the thread.
