Then do we ban cis women who are tall or have a high bone density from women’s sports? Do we allow trans women who don’t have these advantages? Why single out trans people? If you judge that certain advantages are too much, why ban all trans people specifically?
Should I be banned from women’s sports? I mean I’ve been through a male puberty which according to your criteria would seem to make it an immediate no, but I’m also 5’6 and for various reasons likely have a lower than average bone density. Would I be competing with an ‘unfair advantage’?
