While there is some disagreement, as you link to, in general the major authorities on this topic are quite consistent in saying that gender reassignment surgery, hormones, and so forth, can be helpful. For example, here is the APA's page (see the part on "mental disorder?" among others), http://www.apa.org/topics/lgbt/transgender.aspx http://www.apa.org/topics/lgbt/transgender.aspx No treatment is perfect - some people detransition, etc. - and our information is limited, but to the best we can tell, those things do help a significant amount of people. Your being certain that they are hurt by such treatments is both incorrect and unfair. We would need to be EXTREMELY certain in order to deny people the basic right to decide what to do with their bodies. If we are uncertain, we must default to letting them decide for themselves, as it is none of our business. But we are not even just uncertain - evidence seems to point that it can help.
