If there’s any real debate to be had, it’s along the lines of male hormones and penises. Should either be present in a place which essentially only exists for the purpose of keeping those things out?
They are. Every sporting governing body I’m aware of requires trans women to be on hormone therapy for a minimum of 2 years before they can compete in the women’s category. This is completely in line with the medical community’s research into how long it takes before the benefits of being biologically male are counteracted by the hormone replacement.
The debate has been had in the medical community and has been resolved. Now random people who never gave a fuck about women’s sports before think they should have input when they have no qualifications, just because they have prejudices.
Could be, but they would still be required to pass tests to prove their hormones are in the appropriate range, just like cis women have to do when tested for doping with testosterone.
