I have to agree with the medical inclusion, obviously, at least for transsexuals because we simply need those.
The "disorder" part is the same "disorder" that gays, lesbians, polyamorous, African_Americans, women, people who derive from East Asian, Middle Eastern, African (who are non-white,) Jews, Muslims, etc, etc face in USA: a pattern of harrassment, dismissal and demeaning from the majority face. The difficulties that ensue from that do need attention.
That would place the pathology for transsexuals into a medical frame and for other transgendered people it would remove pathology of any kind. Go read the DSM on Transvestic Fetishism! I mean the language is simply heartless!
Virulent hatred should be the "disordered" category. The psychic assistance & pathology, if there are to be some, needs to be geared toward them.
