Blacks are obviously more athletic than whites.
32 out of 32 NFL runningbacks are black. The chances of that happening by chance is over 4 trillion to 1 (4294967296 to 1 to be precise)...and that is assuming that 50% of the population is black.
The average SAT score of blacks is far behind the average SAT score of whites.
If it is ok to say that blacks are, in general, more athletic (which they obviously are)....then why is it not ok to say that whites are, in general, smarter than blacks? (virtually every major artistic and scientific discovery in human history has been made by whites)
