Look, Caster Semenya is not a cheat. Before I continue, I have 2 degres in exercise and physioiology - Lynsey Sharp studied Law!!!
her testosterone levels are within rang. A number of other female athletes who do not dope have equally high levels... and this has been true forever, it is one of the reasons they are good sprinters, weightlifters etc. They simply have higher testosterone levels or their strength training results in a stronger testosterone reaction - and such physiological reposnses are the WHOLE reason for such training, in ALL men and women.
The IAAF has until July next year to submist proper research into the real, specific effects of hyperandrogenism on athletic performance. Until then Semenya is, as an intersex person, raised as a female, a woman!
Sharp is no worse off than any male sprinter whose career coincides wth Bolt, tennis player with Sampras etc, rowers and Redgrave, swimers and Phelps, etc.
If/when the IAAF comes up with something better than "Oooh it's not fair, she's intersex" then some rules will change. Until then, Sharp needs to shut up and keep her unpleasant views to herself. Caster Semenyas position is well known to all athletes, they can choose to be understanding of the science behind law, even/especially if they disagree with it. And it is sodding pointless to be nasty to/about the woman herself, I suspect she would rather not be the 'freak' se is so often portrayed as!
