Of course she has an advantage. But it's an advantage she was born with. She shouldn't be barred from competing because of that advantage any more than we would ban Yao Ming for being 5 inches taller than anyone else on the court, or ban Michael Phelps for being double-jointed in his ankles and chest, or ban Kenyan athletes who are born with physical traits that make them better long-distance runners than anyone else in the world.
Shocking news ... elite athletes aren't like the rest of us. They all have genetic advantages, some more than others. She shouldn't be punished for her advantage. The runners Semenya competes against may not have her testosterone levels, but I'd bet dollars to doughnuts they have high testosterone levels compared to the vast majority of women.
The transgender issue is a red herring. Caster Semenya isn't someone who was born with the parts of one gender but self-identifies as another. She was born a woman. A woman with very high testosterone levels, but a woman nonetheless.
Actually, I'm going to have to correct you on this one... 1) they're not genetic "advantages," they're genetic abnormalities and 2) it's not just elite athletes who have these.
Case in point: How else can one (with no genetic abnormality) logically explain the physiological existence of someone who both a) doesn't think Lochte is a moronic liar and b) insists on [TRIPLE ENTENDRE ALERT] emasculating* Caster Semenya.
