Responding to common transphobic truisms about women in sports for the past couple hours. Result is, some good arguments and references can be found in my profile page.
That's a Lemmy problem, unfortunately. The links are all .ml links because that's OP's home instance, and (as far as I'm know) currently, there is no way to create instance-agnostic post / comment links. Compare https://lemmy.ml/post/19241099/13073901, https://programming.dev/comment/11773309, and https://pawb.social/comment/10354944. They all lead to the same comment (the one that says "Are they?" one level above OP's), but the bit after the instance name is always different, and Lemmy doesn't have a way to convert a "foreign" post or comment ID to a local one. There's an open issue about this on github, though, so maybe this feature will be introduced in the future. If you want to save the comments on your home instance, the only way to do that is to go through OP's comment history.
Given how much effort there has been over the ... centuries? ... to both make rules to create fairness and find ways around those rules to gain an advantage, if Testosterone was the one defining factor for all sports in all situations then there would just be a competitive breakdown for each sport by a player's T-score.
There isn't.
So, much in the same way that combat sports don't have a "bone density" test and sorts boxers, wrestlers, MMA fighters, etc into Bone Density A/B/C/etc classes, I'm very inclined to view all arguments that sports should be broken down by Gender or Assigned Sex At Birth markers to keep the sports fair/competitive, as not very compelling the longer these 'debates' rage on.
