Most of the conversations regarding transgender morality seem to be around cross dressing. These conversations have the advantage of being simpler than transexual or genderqueer behavior. I don't think I have anything to add, so I defer to others. Also, I believe in letting groups self-determine their own rules and not being a cross dresser, my opinion would be less valuable.
