It's axiomatic. The best means the best. Objectively. Fastest, highest, longest, game won.

So your goalpost is a world record? No trans, non-binary, etc. individual I can find has set a world record in any sport.

Participating in the Olympics, only to not even finish isn't exactly winning though.

If we lower the goalpost to 'any trans, non-binary, etc. individual winning gold in the Olympics' again nobody meets that criteria^1^. Dropping it to simply medaling? Again nothing.

^1 Quinn the soccer player arguably does meet this criteria, but it's a team sport. Using that as your sole evidence of 'loads of examples of the opposite' seems extremely cherry picked doesn't it?^
