And evidently that's working so well that trans women are dominating in Olympic and other elite sport?
Well, given that no trans women are participating in the Olympics this year, I guess not.
Nor do you find trans women dominating any elite sport, or even being more than marginally present in elite sport.
The witch hunt is all about something that might happen someday, probably coincident with the sky falling.
Meanwhile in Florida, a a transgender girl who never went through male puberty and is significantly smaller than the other girls on her volleyball team has been hounded off the team and out of school entirely— The subject of a focused chorus of antitransgender howls in her community.
She sat the bench most of the time, anyway, so there was no question of fairness in sport. It was a witch hunt, pure and simple.
And the targets of that hunt don't deserve it, no more than any "witch" at any point in history.
