I don't know her personal story, but I respect her making a choice that is not easily understood or accepted. If you think someone has an unfair advantage, maybe you should ride your bike a little more than your keyboard. Someone who trains harder or is tougher has an "unfair advantage" over a lot of us. Toughness, training, and winning have nothing to do with a penis or lack thereof. You can talk all you want about biological advantages, but I can find a host of women who can smoke the male keyboard jockeys here.
