Caster-away

Several hours ago Caster Semenya received her gold medal for her outstanding victory in the 800m women's race at the IAAF's World Championships. Sadly, that success has been overshadowed by claims that it was undeserved, allegations that she was ineligible for the race,that her competing was unfair to the other athletes. The stage whispers declare her a man and explain her victory with the unfair advantage conferred on her by androgens.

Discuss your thoughts in our Open Thread. Is it fair that we are discussing so publicly Semenya's gender? And how does one determine gender?
