If their sex linked genetics gives them an advantage over women but not men, why should they be restricted from competing against men? That seems unnecessary and cruel.
Because they're neither men nor women. I bet there are physically disabled people who want to compete in no handicap competitions not deemed by the ableist term "special" yet they are forced into that and worse have to accept the obvious that it isn't possible.
Sadly, we live in a cruel and unfair world and coming to acceptance of that is called growing up.
