More than the sum of our chromosomes

My first thought as I read this NY Times op-ed, "The XY Games" was resentment for the sexism behind the requirement that female athletes have to prove they are sufficiently female. As the author of the article points out, merely testing for the presence of a Y chromosome is inconclusive. It seems like the difficulty and scandal in screening out all the performance enhancing drugs and blood doping makes trying to figure out for sure who's genetically male or female not so relevant. The Greeks had an Olympic gender test too lest any girls try to sneak in. Change is a long time coming. If an athlete who knows inside he's male wants the gold so bad that he's willing to sacrifice his male privilege on the altar, goddess bless him.
