IOC OK Transsexual Athletes in Olympics

Athletes who have undergone sex change operations will be eligible to compete in the Olympics for the first time under new rules being finalized by the IOC.
...
"We will have no discrimination," IOC medical director Patrick Schamasch told The Associated Press on Thursday. "The IOC will respect human rights."

Pat's damn diverse, isn't he?

But here's the best part:

Until 1999, the IOC conducted gender verification tests at the Olympics but the controversial screenings were dropped before the 2000 Sydney Games.

One reason for the change was that not all women have standard female chromosomes. In addition, there are cases of people who have ambiguous genitalia or other congenital conditions.

I'm so confused! Why not skip all the fooling around and just have unisex competitions?
