morning reading: gender testing

I'm not an avid sports fan so it's no surprise that I was totally ignorant about the gender testing Olympic athletes have to undergo. Granted, Olympic competitions are divided along gender lines so officials have to be as fair as possible. At the same time, the extent of these genital and chromosonal tests seem violating. Indian runner Santhi Soundararajan was recently declared "not a woman" because she has an SRY gene. As a result, she may lose the silver medal she won in the Asian games. As gender becomes increasingly indeterminate (afterall their are a number of intersex and trangender people, etc.), will we (Americans) be able to adjust our fixed ideas about gender and sexuality? We can't even manage to legalize same sex marriage in this country so it's clear we have a long way to go before we can conceptualize sex/gender in more evolved ways.
