But there is no research suggesting that trans girls have an unfair advantage in school sports
Even without knowing the specifics of how much advantage going through a male puberty confers throughout a lifetime, there is a significant difference which is not often talked about.
Elite Sportswomen - like elite sportsmen - have to work so hard to maximise their athletic potential, putting hours into training, diet, psychology, understanding their bodies, menstrual cycle etc to push their female body to the absolute maximum.
On the other hand, elite TW athletes (and those with male DSDs) are being asked to take hormones/drugs to minimise their athletic potential. Be 'less good' than they naturally are.
They can also be significantly older - decades even - than their natal female opponents and still be contenders as they are no longer at their male physical peak.
These male athletes are required to have lower testosterone levels to prove they are now so 'bad' at sports that they can (potentially) be beaten by women.
Having said that, is there any evidence that the male teenage runners in girls' races in America are even using blockers/cross sex hormones or are they just easing off in some races?
It’s the antithesis of all other elite sport where athletes are pushing their physical bodies to the absolute limits - and so very disrespectful to the female athletes - as the message is: 'Be (quite a bit) worse than you have the potential to be - and minimise rather than maximise your performance - and you can still win'.
Grew up with The Guardian and loved and bought for years but felt a sea change after Cologne. So disappointed by Katherine Viner's instincts as editor, I now probably wouldn't bother picking it up for 'free' with a Waitrose shop if it was the last paper left...
