Maybe, however before puberty I don't think the child's gender identity can be properly pinpointed. Children, and teens, are often confused about that or are often hard to fit into neat categories. That doesn't mean that once they're adults they won't fit right in. I think transitioning a kid amounts to child abuse.
Do you think that
reversibly postponing puberty until a child reaches a socially acceptable age of majority so that their bodies don't make an
irreversible choice for them is child abuse?
Because that is what is done by any reputable therapists and endocrinologists in the field. They are prescribed androgen blockers which
delay a change which all evidence shows that they do not want. And even that is not done casually.
Transgenderism isn't some new fad. It has existed and has largely been accepted by most non-Judaic cultures for all of history. The
dysphoria isn't a result of being transgender. It is a result of the social strictures forced on the transgendered by social systems which are intent on finding them somehow broken or even abominations.
Just because someone is a child does not mean that their evaluations of themselves are without merit and can be casually dismissed. There is a difference between 'tomboys' or 'sissies' and children who are transgendered.
Their input deserves consideration and review. Kids are not just given fistfuls of hormones because they say they want to try being a different gender. Years of counseling are involved. But their bodies don't operate on the same clock as society's legal definition of competence, and when puberty sets in there is no going back.
It
is 'child abuse' to force them to be trapped in a body they detest when there is no significant physiological cost in preventing that.
Especially when compared to the psychological costs implicit in refusing such treatment. If you are at all interested in the causes of high rates of suicide in transgender youth that's a good place to start looking. That and the social rejection that goes with being trans in the first place.
That ostracism isn't the sort of thing that a child would
choose to be subjected to. There is no good reason to force them to deal with having their bodies against them as well.
