You bring up a lot of valid points, however the main reason I brought up that quote from the article was to highlight that the concerns people have aren't unfounded. There may be ways to mitigate it, but I think we can all agree this is still an evolving space.

Ultimately, women sports was created to provide a space for "women" to play sports. I put women in quotes because from its inception women sports was used to discriminate between people an in group (women) and an out group (men). So the question is, does "women" mean AFAB, post-op trans, people who identify as women, men? No matter how you slice it you're going to be discriminating, the real question is, what group are you protecting?
