Perhaps I could draw together what you, I and
@Backup have been saying. In discussion with me you raised the spectre of the insane policy of allowing the whims of children, 90% of whom change their minds, to drive the transition process. This process was presented as a package, pronoun and name change, bathroom use, drugs, surgery, the whole nine yards. You describe this as medical malpractice and an insane representation of modern liberal thinking leading to harm.
Now it seems that, like all spectres, this doesn't actually exist. The 90% you refer to, don't actually do any transitioning at all. They desist, having put their toe in the water, they realise that this is a serious business and change their mind. I note that you don't give any credit to the professionals advising them for helping them come to this decision. According to you, all teachers and medical personnel are balls out for the maximum number of transitions and seek to encourage youngsters to go as far and as fast as they can.
What we actually have is a society where teenagers feel safe to explore these aspects of their identity, both gender and sexuality, in a way that was never possible before. This is a good thing. That only a few of those who toy with the notion of transition to a different gender actually go through with the idea, is not unexpected, and is itself a good thing. That those who genuinely feel that transition is for them and go through the process, overwhelmingly decide that this was right for them in the long term, is also a good thing. In short, despite your horrified bluster, what the regime in schools and medical practice is actually producing, is a good outcome. Current policy and practice is working. Stigma is reduced, acceptance is increased, society as a whole is more tolerant and people are happier.
Finally, a word on mental illness. Trans people are much more likely to have depression, anxiety and other mental illness. Their primary condition, that they are trans, is not a mental illness, it isn't a symptom of mental illness, it doesn't cause mental illness, nor does it indicate that the individual trans person is mentally ill. It's not surprising that the upheaval to the psyche of contemplating, then going through with such a radical reinvention of the self, is likely to have attendant problems. But frankly, so what? We can as a society do our best to make that process as trauma free as possible. We can and should remove stigma and applaud bravery. We can treat depression and anxiety, which are not exclusive to trans people. One in four adults will experience mental ill health at some point in their lives. Rather than merely pointing at the extra mental health burden on those who transition genders, we should be doing something to help. To say that some of the comments and attitudes expressed on this thread are unhelpful, would be an understatement.
