That certainly seems to be his position, and even though I disagree with him myself on many subjects, where is the evidence that he is wrong on this question? I have no idea whether he is right or wrong regarding the short term or longer term benefits or adverse effects of surgery, and I suspect you don’t either. His opinion is based on evidence though, although admittedly from decades old studies. He is not some guy on the street though with an opinion, he was the President of the Department of Psychiatry at Johns Hopkins from 1975 to 2001, one of the leading medical research facilities in the world, hardly a position you obtain and retain for 26 years without some bit of competence.
You characterization of him as holding opinions based on disgust as homosexuals and transgenders really doesn’t hold up to scrutiny. In his position he would have overseen the sexual behavior clinic, one of the most respected in the US, a clinic that has helped many thousands of patients with sexual problems but also treated some of the worst sex offenders, including pedophiles, in the country. He would have encountered plenty that would disgust most people. I doubt his motivation was disgust in developing the methods developed at John Hopkins, and outlined in his landmark book “The Perspectives of Psychiatry”.
So, fire up the evidence that surgery actually has benefits in terms of treating the medical condition known as gender dysphoria. McHugh points to studies showing that 10 years later significant levels of mental problems (anxiety, depression, suicide) exist. Where are the studies that show symptoms are actually alleviated? I haven’t been able to find any.
The second and more significant issue I have is with your (and others) offense at gender dysphoria being characterized as a mental disorder or illness, which is was up to very recently. You are falling for the argument that there is a stigma associated with mental illness, failing to see that the problem is the stigma exists at all in society. There is nothing “wrong” with mental illness, no more than there is anything wrong with cancer or diabetes. In fact there is a very good argument to be made as to why gender dysphoria should be delisted as a mental illness, but anxiety disorder, OCD, various phobias, depression, panic attacks, etc. continue to be listed as mental disorders, if all of them are due to how the brain processes stimuli. Does the listing of these as disorders stigmatize them (it shouldn’t surely). It doesn’t really hold up to rational scrutiny, leading to the conclusion that the LGBT lobby were successful in removing it from the DSM-V as they didn’t want to be associated with people with mental disorders (surely adding to the stigma of mental illness?)…
If you think about it rationally a transgender person has a mismatch between their body parts and the way their brain processes stimuli to create gender identity. So, is the medical condition wrong body parts leading to anxiety and more serious mental disorders, or a brain that is miswired and reads the stimuli wrong? I’d be inclined to tentatively believe the latter, which would suggest to me that treating the brain (via neuroplasticity for example) might be more successful than surgery. There are lots of studies that other brain wiring conditions such as OCD can be helped by neuroplasticity, it just seems a little less invasive than chopping off genitals.
