While I sympathize with Trans-athletes, my sympathies lie more with natural women athletes.
We don't see female to male transgenders going into male sports and dominating.
We see the exact opposite happening with male to female trans-genders.
You can take all the hormone blockers you want NOW, but it doesn't change the fact they've had a non-zero amount of time (sometimes decades) of development with male hormones giving them a competitive advantage. You don't immediately lose bone density, muscle mass, the ability to activate muscle responses by taking hormone blockers. Maybe after decades of hormone blockers you erode those advantages. But not in a year, or two years, or five years.
So I have almost no sympathy for male->female transgenders who enter competitive sports like weightlifting in the women's class. They're blatantly ignoring biology because it's going to help them win, and calling people bigots for pointing that out. They want the success and recognition representing transpeople in sports while stomping all over the rights of biologically consistent athletes.
I don't like "separate but equal" but in this case I don't see much alternative. We need a transgender class for sports, period. It's the only fair thing for biological women who are getting completely overshadowed by people who transitioned a year or so ago. There is already plenty of evidence of transgender women entering competitive female sports and crushing pre-existing records because.....they've still got the competitive advantage of a male. It's in no way fair, or sane, to pretend otherwise.
