there are people living in our society who have transitioned and are happier and healthier for it
And, obviously, there are those who are not.
Many detransitioners talk about their feelings of betrayal, that adults enabled them and did not protect them from these decisions that with hindsight they believe they should not have been allowed to make, or from the permanent damage they now have to live with.
The basic question is:
Is it more moral, ethical, responsible and right to do something that will permanently change a child's body and cause potentially serious life long medical issues and harm, knowing that some of those children will come to regret it and struggle to live with the permanent, inescapable after effects and loss of adult potential?
Or is it more moral, ethical, responsible and right to say no, medication and surgery cannot ever be accessed by children, and is territory only for adults who are able to make such permanent decisions, knowing that some of those children will be frustrated by the wait?
