This had the potential to be a great episode, and I loved hearing Ember's story, but I think the framing of it misses the mark, unfortunately. By looking at this story as "trans people aren't dominating, so why are politicians so concerned", you're actually giving credence to the anti-trans viewpoint. Because the implication is that if they were dominating, then these bans would make more sense. This is purely a human rights issue; women should be able to play women's sports, regardless of how well or poorly they perform.
Furthermore, your closing notes about how "testosterone" is a meaningful consideration and should be used to determine who can participate also is a first step to the anti-trans viewpoint. Trans women are women, full stop. At the absolute elite levels, sure, put in some timing requirements (must have been transitioned for at least X years under some medical and psychological definitions), but once you introduce hormone testing or anything like it, you start legislating "what is a woman".
I really do think this episode was done with all the right intentions, but allowing these talking points to be taken seriously is how we've gotten this far already.
