I think most people on here (and gendercrit people and radfems, three overlapping but distinct groups) agree with this. There are some rare people with a mental problem that expresses itself through serious, life altering distress over their body's sex characteristics. For some of these people surgery and hormone treatments may be their best shot at being able to cope with their mental illness and have a decent quality of life. But no, no one who's paying attention can really believe that all of the Aydens on tumblr or Lilys on reddit are suffering from this rare mental disorder.
