Is transgenderism a fad that's going to die down?

I've watched a lot of videos of detransitioners, and I think it's horrendous that they allow children to stunt and even mutilate their bodies because they "feel different". I'm not anti trans, and I fully support grown adults doing whatever they want with themselves. Not children though, no fucking way. Those situations need to be handled differently- without puberty blockers and god forbid surgery for fucks sake- until they are 18, 100%.
