I am still opposed to them because they're driving a moral panic that hurts trans people in other ways, because it's part of a wider drive / overton window shift to making life as a trans person impossible in these states (including declaring our existence as "sexual", banning us from most public places children could be), because there are still some trans people affected (or their ambitions are quelled) and, here's a reason you, who has given me no indication of asking in good faith, should care about: Because cis girls that anyone suspects of being trans are subjected to actual, and i can't believe i'm writing these words, genital inspections. What a stupid question to ask.
And please, stop pretending like trans women and cis men are a 1:1 comparison. We have trans athletes. Use them - in aggregate and not with an anecdote - to make your comparisons and you'll see it's pretty much a normal distribution of performance. In fact, you're making my point for me, because even the most salient of examples still get beaten by cis women. That wouldn't happen if we had this immense disparity.
