I agree that at 9 they might not "fully" understand, What I was saying is let them grow and develop who they are on their own. The chances of adult LGBT activist having a child that is trans is quite improbable but not impossible. I'm not talking about them taking meds at 9, or having procedures done. I also agree that they need to develop more mentally. I would never refute that issue. The one thing I'm not sure on is waiting for hormones till they are 15-16. By that time I was in a D cup, and looked like I was out of high school. But girls as young as 13 can get on the pill and that's okay? Because that's how it is.
