As I said, we can’t discuss it from a theoretical point of view. The way I would go about it is:

• Trans athletes in their specific fields are outperforming all cis athletes
• The roster is filled with trans athletes basically

Those conditions would indicate that trans athletes are in practice having their own competition that excludes cis athletes. And this would be the starting point for discussions, not a reason for segregation. Top athletes are more likely to have a constitution that is out of the curve, but that is not enough to guarantee top spots. They have to work for it as well and most cis athletes advantages are just celebrated, instead of the criminalization we see when trans athletes excel.
