OP, I've just spent a few hours reading the stories on reddit/detrans. And I actually cried. Do you want to know why?
Because, on-site, there's countless first-hand accounts of people who decided as children, that they were trans, all of which eventually de-transitioned, and the majority of these people all say similar things:
they wish that somebody, anybody, had gently explored their issues with them and hadn't just assumed they were trans.
All of them had reasons for wanting to transition: they were groomed by older people to think trans was the answer to their problems, they were immersed in online communities encouraging them to consider their gender identity, they wanted to protect themselves from further rapes, abuse and sexual exploitation and thought that transition would be the ticket, they talk about internalized homophobia, about how they were pushed into identifying as trans based on outdated stereotypes about what boys/girls should do and feel, they had autism and were misfits and a new tribe told them they would fit in 'here'...
It didn't help these people. Some of them mourn their missing wombs, their excised breasts, their removed penis' that they never even had the chance to use.
These people are not lying. They all wish that somebody had helped them explore their reasons for being trans rather than simply accept their declarations and push them into the medical pathway which, as de-sisters and de-transitioners, they woefully regret.
If you're an adult and have crippling gender dysphoria and you think that medical intervention will help you be less dysphoric, then I'm okay with that.
But if you're a child, making big decisions which legally you cannot begin to understand the eventual repercussions of, I would hope that somebody, somewhere, would gently explore the reasons for your decision to transition with you, unpick that internalised misogyny and homophobia and self-hatred and address those comorbid psychological issues before you made a massive, life-changing decision that you may very well regret.
That's not 'conversion therapy': that's good therapy.
