I've always wondered why stating that blacks are better at certain sports is not considered racist toward other races?
Anyway, when people and scientists are punished for expressing thoughts just because some find those offensive (think about Darwin, Freud, and many others), then we're turning the wheel of history backward. More and more so, we're living in times when people are becoming afraid to freely share their opinions - motivated or not, scientific or not. The only true way to prove somebody wrong is use science and not twist their arms (or tongues).
