OTOH very little of how our society bases its treatment of trans people based on science or medical prognosis. The best evidence there is is that dysphoria is real and gender affirming therapies including medical transition is an effective treatment. Yet access to that treatment varies extremely widely, being treated inherently as a second or third class citizen both by culture and in a lot of cases by law.

I do understand as well your reticence around the ideological space that a lot of online spaces take place in. To that I’d just say that this stuff is fairly new, and you have a lot of young people finding and differentiating their identities as they’re going through quite a process.

My opinion is frankly it’s a wonderful thing, to have it so people can prioritize their emotional well being enough to not have their natural individual differentiations beat out of them as so many cultures have done. In doing so, discovering how much of a thing gender dysphoria is for some, and allowing them to lead much much better lives.

Per your last point, the response can swing the other way and also cause harm in some cases: https://www.bbc.com/news/health-51676020

Yes, and detransitioners happen and should be (and are as far as I've experienced) supported. But their argument a bit like if I said that all elective surgery should be illegal because I regret mine. For every story like this you can find a thousand who are waiting years to get any amount of treatment. The UK is well known for having some of the most stringent policies and heavy usage of gatekeeping before anyone gets treatment - FAR more than in the US.
