why is it that if a woman does well... she must be a guy..
so the olympics, london, and women.. this thread fit the criteria...
some women athletes like Caster Semenya, from south africa are being investigated for being too masculine ...

Since women began competing in the Olympics in 1900, their femininity, or lack thereof, has inspired the creation of gender verification tests.
In the 1960s, female athletes had to walk nude in front of a panel of experts who assessed their sexual credentials.
The so-called “naked parades” were abandoned and gender verification was eventually done using chromosome tests, until the IOC called for their discontinuation in the late ’90s, saying the tests constituted an invasion of privacy.
