humphrey or maybe people realise that sport was never fair in the first place?
Of course it is hideously unfair for men to compete against women. Just as it is hideously unfair for people who are 6 foot 5 to compete against people who are 4 foot at high jump. It is unfair for anyone to have to compete against Usain Bolt or Phelps.
Everyone who ever made it to an olympic final had a massive unfair advantage over the average human, in their hormone levels, their bone structure, their tolerance to pain and training, their lung capacity, heart function, muscle structure etc.etc.
Saying you can have a separate category for XX individuals doubles the number of winners, but it didn't at any point make it fair.
In trying to make it fairer on for all sorts of intersex conditions the lines got sufficiently blurred to allow XY individuals with either super low testosterone or a way of depressing their testosterone fit at least partially in the category too.
I can just about see the point of having an XX category - but no one should ever think that has any impact on the fairness of sport, which is non-existent.
