If anyone here wants proof for how ludicrous anti-trans sports bans can be, the state of Oklahoma has sent out a warning to All Elite Wrestling for having transwoman wrestler Nyla Rose wrestling against a ciswoman wrestler Alejandra Lion.
As in pro wrestling.
As in that sport that is scripted and not real. The sport where the fighting is choreographed. The sport where no one has an advantage except the people the writer thinks should win.
this is a way better model... you'll still get transphobic & intersexist drs of course but i prefer this to male / female or even having separate questions for gender & sex.
[we can't see the full form, but i'd suggest having a "something else" option and dominant hormone question too.]
