US Authoritarianism

The issue itself is nuanced, unfortunately the debate is not.

Transwomen who've only gone through female puberty (i.e. transitioned as minors or went on puberty blockers) are going to be physically on the same level as ciswomen.

Transwomen who've been through both puberties are going to be pretty close to the physical abilities of the average ciswomen after a few years on estrogen, though there are some permanent effects of testosterone that will remain, like build size.

Thats to say nothing of the fact that dividing sports along gender is somewhat arbitrary to begin with, while the average female athlete may be smaller and weaker than the average male athlete, there is still plenty of overlap, and it would really make more sense to divide sports along different criteria, like weight classes or some other more fair metric.
