Those excerpts are interesting Cigarstring. I think what we see there is a doctor very closely (too closely) identifying with their patients and perhaps entering the role of rescuer, where they will do anything to soothe the feelings of distress they see in front of them - an understandable human reaction, but not an objective one. I think their boundaries are not solid enough, and certainly they have little care for the consequnces for others.
I personally know how hard it can be sometimes to keep to the path of sanity and sense in the face of enormous long term psycholgical distress and severe MH issues, but keep to it you must if you want to help someone.
I posted something on another thread about how to deal with delusion and challenging beliefs and the 'rules' are not to appease or go along with, in the same way that we do not go along with anorexia. But that robust challenges usually entench the delusion. It is not easy for sufferers or people around them.
Social transition may help those with sex/gender dypshoria as a stabiling strategy but medical procedures were always meant to be a last resort, not something normal.
Lots of people have difficulty in coming to terms with a medical diagnosis, especially MH where a person's state of mind will naturally already be upset. But I don't think we shoud aim to reduce stigma by redefining, minimising or normalising the illness or disorder, (though I can of course see why sufferes would not want to 'not normal', and especially where theree has bene past abuse), but we can change people's understanding and views, including patients and encourage compassion for the distress it causes, not say that it is just a natural variation like ginger hair.
