Blacks totally dominate sprints and hurdles, tho every now and then a White kid will win. Richmond Flowers may have been the best hurdler in the world in his day. Valeri Borzov won the 100 meters in the Olympics as did Alan Wells of Scotland. Wells did have the advantage of the American boycott in 1980 but all the Jamaicans etc. were still there.
I was a pretty good hurdler in college and I would often be the only White guy in each heat.
Well now since half a century of virtually every American sprinter (male or female) being black, I think people are irritated and fed up with having been lied to. It's just a matter of fact that on average blacks are faster than whites. It's too ridiculous trying to debate the subject as mathematically it would be impossible to have the kind of dominance in athletics blacks have if the races were equal in athletic ability. And pointing out the odd fast white guy won't work as an argument. People have to face reality.
