Speaking for myself I believe that trans people and non-binary people should be accommodated, but there’s a contextual limit. When it comes to equal protection, employment, healthcare, medical access, bathrooms and a dozen other issues it’s a no-brainer in favor of accommodating people.

Ironically the sports divide is probably the single area where having some physical advantages isn’t a bonus. It’s also near and dear to the hearts of billions, and such a terrible hill to die on. Ideally the solution would be a league like the Paralympic competitions, but high level athletes are rare, trans people are relatively rare, and two overlapping are incredibly rare. To make such a league would be a farce that couldn’t hope to succeed.

In the Olympics, it appears trans athletes are still a minority among the group of athletes who are excluded because of sex characteristics. Most of the athletes impacted by the ever-stricter testosterone limits in the Olympics are cis women. Such a league would include cisgender former Olympic athletes who had to undergo forms of HRT in order to qualify.

When discussing trans people in sports, the most salient contexts aren't elite sports championships like the Olympics. "Sports" is also done recreationally and is often considered a normal part of ones childhood upbringing. On the topic of trans people, the question "can my child play this sport with their friends"?
