I don't pretend to know about the feelings and thoughts of CDs,and I agree there are significant differences between them and us. However, haven't many MtFs first identified as CDs?
Maybe I'm wrong about this, but I don't believe everything is as simple as one has to identify completely as male or female. I believe many CDs have a "core" male gender but also have some female brain activity. And no, for some, I don't believe it is as simple as "switching the female part on and off" whenever it's more convenient to be a man. I once had two dear friends who were CDs. One, was the way I have just described- male core identity, but also felt somewhat like a female. The other, well, I really suspect that he was late-onset MtF. He said he felt like a woman and wished he were a woman. I don't know for sure, but I think he was afraid to transition because he knew that not only would he never be able to pass (he was extemely masculine in appearance) and therefore face ridicule and the threat of bodily harm everywhere he went, but also lose his children and the business he had spent his life building.( because he'd probably lose many customers). He has since passed on (both of them have), and it breaks my heart that he was never able to be the woman he felt he was. I wish people (trans and non) would not be so quick to judge CDs. Remember, some CDs may really be MtF transsexuals who have not come to terms with their condition or for reasons of their own, will never transition. I do NOT buy into the myth that a "true" transsexual will transition or die. For some MtFs who will never pass the risks outweigh the benefits. One thing that bothers me about some transpeople is their belief that we're all the same. Some people are stronger than others. What may be right for one transsexual may not be right for another. Everybody knows non-transsexuals are not all alike. Why should it be any different for us? In short,transgender is transgender, transsexual is transsexual, not the same, but really not all that different either.
Just my humble opinion.
