Interesting, I've never heard the term "gestating person" before. That kind of sounds like a term that the TERFs would come up with.
As for the whole sports debate with trans women competing in womans sports, the medical science behind the issue is that if a trans woman has transitioned and been on testosterone blockers and estrogen therapy for a couple of years, that person has already lost about 15 to 20 percent of the muscle mass that they had before transition. If they've had surgery to remove the source of testosterone production, the muscle mass loss is a bit more. That removes any advantage that the trans person might have previously had due to physical strength. This is something that rarely is part of the conversation when the right wing fanatics are pushing their agenda. The Olympics governing board has already addressed this controversy, that's why testosterone tests are done before competition. Testosterone "doping" gives any woman an advantage over the other competitors.
