Are you arguing from the point of view of law? I am.
Should it be illegal for sports to allow TW?
To compete in the female category if they have gone through a male puberty? Yes.
To compete in the male category? They should be absolutely be welcome and encouraged to do so!
Should individual sports associations change the rules?
It should be a government ruling to protect female sports.
Should girls and women boycott sports which allow TW? And further deny and restrict their opportunities? When the science is there already?
Do spectators (male or female) tend not to watch sports with TW anyway? if people are not allowed to discuss, how are spectators to know which sports they should and should not be watching?
Why not just make sure that people don’t have do extensive research on the sports they are supporting and watching to choose to support female only sport?
Why not make sure that males are excluded from female sports until some miraculous solution has been found to make it fair in some way?
