    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 & concepthttps://twitter.com/PeterTatchell/status/1186289803526062080 …

    Preventing trans women from competing in sport is denying their human rights. Most athletes have some form of advantage, such as fast-twitch muscle fibres, large hearts & lungs or extra long legs. Why single out trans competitors? https://www.cyclingweekly.com/news/racing/preventing-trans-women-competing-denying-human-rights-transgender-athlete-rachel-mckinnon-returns-defend-track-world-title-440713#YcXIv2c8K4qvKXlm.99 … FOLLOW @MunroeBergdorf

        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

        I’ll grant you that biological sex is a powerful performance determinant, but the traditional binary view of sex is no longer accurate. There are more than two weight classes. Junior and senior world championships. Maybe we need to expand the sex categories beyond the binary

        If you have an evidence-based way to do that, lay it on me. Also, biological sex IS binary. The perhaps 1 in 10000-20000 intersex cases don’t disprove that. In those, attributes creating sex remain binary, they just don’t align. MTF aren’t those (cc: @FondOfBeetles @SwipeWright)

        If biological sex is not an advantage, is it likely that we will see trans men beating their biological counterparts in sporting endeavours such as athletics, cycling, swimming, etc?

        I’m not sure I follow what you’re asking here? If biological sex is “NOT” an advantage, then women and men would perform equally. I don’t know what you’re asking re trans men? You mean FTM?

        Approx. 10% difference in pretty much every sport between 'similarly' trained elite males and females. That's a huge advantage, and one that could not, ever, be matched by combining advantages from fast-twitch muscle, long legs, etc. It's a ridiculous statetment.

        Bigger than that. In weightlifting, it’s 30-40% even after you correct for mass. It’s only the swimming, running events that are that small. Throwing is similarly much larger.
