I’ve lost count of how many times this argument is made, but it’s as ridiculous every time. Biological sex, not identity, is the reason for separation because it’s the most powerful performance determinant. Other physiological attributes differ enormously, both in scale & concept
Right or wrong, we don’t ‘protect’ short-legged, slow-twitch, small-hearted humans in any sport. We DO protect lighter mass in contact sports (for good reasons), and Paralympic sport has categories to create meaning through fairness. Separation by biological sex creates meaning
So that’s why biological males are "singled out”. Not doing so removes meaning of sport for those who don’t stand to benefit from androgen advantages. Until evidence emerges that hormone suppression for 12 months (or whatever duration) removes those, the status quo must remain.
And if one day, sport decided to create categories for “short" basketball, slow-twitch sprinters, small-lung and -heart marathon runners, then it would absolutely be required to test those attributes in every participant, otherwise cheating WOULD occur. We wouldn’t accept self ID
We would not allow the 2.01m person to play in the under 1.70m NBA. Even the 1.72m player should be turned away. "VO2max over 65? Sorry, you run over there”. Similarly, with biological sex, an even more powerful physiology, we are obliged to regulate (or deny) to ensure fairness
