I heard a psychologist say in an interview that over 90% of children with gender identity issues grow out of it. Many of them though realize that they are gay. I feel bad for kids whose parents start giving them sex hormones at such a young age before they're capable of making that decision. That used to be called child abuse and now its the Standard of Care.
Adults, even mid teens, have the right to make their own decision in that regard. But there is no way that adults have the right to interfere, and interfere permanently, with the natural physical sexual development of an individual, of a child. Someone who can't possibly be expected to understand the implications.
What's happening is child abuse.
