Look, I don't mean to be rough, and I'm sorry if you are new to the field of transsexualism and feel like you just stumbled into a minefield.
That there be some form of psychological assessment for stability prior to surgery is, unfortunately, in this litigious society, not entirely unreasonable.
If assessment for Genital Reconstructive Surgery is to be like assessment for Bariatric surgery then that is not incompatible with what the activists are demanding. And that process begins with removal of GID and its brethren from the DSM.
We don't after all require diagnosis of Cancer Identity Disorder or Obesity Identity Disorder as a condition of surgery now do we?
All transmen ask is that they be treated like non-transmen. Corollary for transwomen. It is not to much to ask and they have given up on taking no for an answer.
If GID is not removed from DSM/ICD by medical authorities it will be removed by government edict. Sweden did this on 1/1/2009 for children, France did it on 5/15/2009 for children and adults, more will follow soon enough.
