I don't suggest that. I suggest denying trans women opportunity to (professionally) compete. I believe this is inherently discriminatory, but better than all other alternatives.
I also believe this is 99% smaller problem than anyone talking about it believes.
They can still compete with the other men. The only difference is that they won't get the affirmation they crave from competing against actual female women. But that's their own personal problem to deal with in their own minds.
