People always say that the decision is up to the child, parent and doctor but you literally can't be a professional in the field of approving sex change surgery and hormones for children.
Normally a doctor approves a surgery because there is something wrong with the kid. Like lets say the kid has a deviated septum. They diagnose that the septum is deviated and offer surgery if it is causing problems with the child. The parents approve of the surgery and the child gets the surgery because it's medically necessary.
With gender and hormones, there is no proof that the kid was born in the wrong body. The only possible diagnosis is simply believing what comes out of the child's mouth. Children can lie, be manipulated and be persuaded. Approving a life changing surgery for a kid based on their word is medical malpractice. There isn't a human on earth that can accurately determine every time a child is lying or has been manipulated or persuaded into saying something that isn't true. Hence why it is impossible to be a professional and why the liberal excuse that the decision should be up to the kid, parents and doctor is total horse ****.
