I don’t know anything about schizophrenia, so I can’t answer that for you. But I believe strongly that the classification, diagnosis and treatment for it is a question for the medical professionals working in that area and the people with the condition to sort out.
Except now we are discussing treatment for children too, not just consenting adults. The moment our children are involved, most of us will not allow this to be brushed off with appeals to authority.
Not to mention that authorities are regularly wrong, e.g. lobotomies.
I have never seen anyone advocate irreversible treatment for children. The only thing I have ever heard of is delaying the onset of puberty so that if they decide to go ahead when they are adults then they will have the best outcome, and if not they can cancel it at any time.
Delaying the onset of puberty appears to have long-term effects. More importantly, this is very early and the science is still coming in, and therefore such treatment is effectively criminally negligent; our children should not be walking experiments.
And yes, we as a society shall discuss precisely that, whether activists and elites with fashionable ideas like it or not. Which brings us back to the biggest bookstore on the planet...
