That doesn’t seem like an article so much as the ramblings of an uninformed racist.
He seems to have forgotten the countless athletes of all races (not just black and white) that have been caught doping. There’s no mention of the Soviet and East German doping programs. He also seems to have forgotten Ben Johnson.
He doesn’t actually make any arguments which support his claim (I dare not call it a thesis) that while athletes don’t take steroids.
I feel dumber for having read that.
