Just playing the devils advocate here.... You've made no valid point other than pointing towards dictionary definitions. First You assume every psychiatrists backs that model. Second you say that because a phyciatrist said it its true it is; medicine is a forever evolving thing and we are just breaking the surface. Also phyciatrists are probably of normal intelligence in comparison to other practitioners of science, for instance physicists. Negating the huge intellectual jump between the masses and phyciatrists. Thirdly, using the logic of majority wins ( if I huge number of phyciatrists say it so than it is) is not a a truely logic base for something with such massive ramifications ( if trans were considered a mental it could be detrimental to your happiness).

Thanks for your time Donald trump.
