I'm warming over the same arguements because they are strong and perhaps have no satisfactory answer.
That's because mental health and its causes are very difficult to pinpoint.
I believe if transphobic abuse is greatly reduced many people may not feel the need for medical intervention.
We can not know how much of a factor this plays into sucides in trans people.
Also it is still seen as socially unacceptable for people to crossdress in public. So people may feel the need to go through this treatment just to feel socially acceptable dressing the way they want.
You are probably correct in your views but my only argument is that there is a debate to be had on this. Because these trans issues are not understood well.
