If you are born a certain sex, you should compete in the same sex category provided you haven’t taken any substances to enhance performance. This would mean you are only using what your body naturally produces.
Theres a difference between trans-women and women.
Being trans isn't a choice, but taking testosterone or whatever definitely is. It does not matter if you're male, female, trans, chinese, african or american.. Nobody should be allowed take banned PED's in professional sports.
It is very important to keep this integrity in sports. You could argue that you can let a FtM take testosterone because else he wont be able to compete with the others, but what if he started winning. Will people say he won because he's so good or would it be because he's allowed to take testosterone?
No ifs, no buts.
I disagree. You just cannot be caught taking steroids/testosterone. Plenty of athletes do it and get away with it. Its part of the game, a meta game if you will.
