Caster Semenya is fast and strong and far from dainty. When it came to light last week that an athletic organization was secretly testing her sex, the sports world and mainstream media got a refresher course on an important reality: while our society tries to strictly divide people in male and female, the science of sex is far more murky.
South African Semenya is shaping up to be one of the fastest runners in the world, but if the International Association of Athletic Federations' (IAAF) forced battery of tests (including a gynecological exam) find she's too "male", she could be stripped of her medals. The IAAF stopped mandating the outdated sex tests for athletes back in 1992 and the reasons for testing Semenya range from
fairness to
racism, depending on who you ask.

Over at the Huffington Post, Jane Devin
points out that males whose genetics make them sports stars are groomed and applauded, not subjected to embarrassing tests. You have to ask—if Semenya had thinner shoulders and a more delicate chin, would her competitor's allegations ("Just look at her," sniped
a fifth-place finisher at a recent race) be given legitimacy for even a second? I think not.
