For all those using the 'but they grew up believing they were female' argument. This is simply an emotional appeal. It is manipulative to use it. And frankly, if you were convinced by this argument to prioritise those male athletes, it says more about you than it does about us who ignore it.
People find out things about the bodies that they have to cope with every day. Things that completely change their lives. Why have you chosen to elevate this group of male athletes?
The only reason to keep bringing 'they grew up believing they were female' is to try to convince people to have more sympathy for those athletes and give them additional rights over female athletes. There is no other reason for posters to keep bringing up these male athlete's background as some special consideration to abandon the need to protect female athletes.
And if a person chooses to compete in a protected category that they know that they have an advantage over, why the fuck should anyone respect that athletes choice?
