The best evidence is that the core nucleas of the siriata termanalis, in our brain, is wired up in female mode. There is nothing you can do about that, but accept the hand, fate dealt yo.,

Sorry Chrissiegirl I just can't keep reading the same errors of fact repeated over and over. The structure you mention is the "stria terminalis," and what you have referred to as being "wired up in female mode" and by inference implicating it as being responsible for gender identity, is ONLY a THEORY, and not even a strong one at that. Here is a description of a single study (hardly overwhelming evidence) with ONLY 6 MTF and ONLY ONE FTM subjects (hardly a representative sample of the population at large, or even the transexual community):

The central subdivision of the bed nucleus of the stria terminalis (BSTc) is sexually dimorphic. On average, the BSTc is twice as large in men as in women and contains twice the number of somatostatin neurons.[5] A sample of six male-to-female transsexuals taking estrogen were found to have female-typical number of cells in the BSTc, whereas a female-to-male transsexual taking testosterone was found to have a male-typical number.[6][7] The authors of those studies indicated that the finding could have been because of the hormones being taken by the study participants or because the stria terminalis causes gender identity. However, the authors also examined subjects with hormone-related disorders and found no pattern between those disorders and the BSTc while the single untreated male-to-female transsexual had a female-typical number of cells. They therefore concluded that the BSTc points to a neurobiological basis of gender identity disorder. However, in a follow up study by the same group, they found that the sexual dimorphism of the BSTc is not present before adulhood (approximately 22 years of age) even though transsexuals report being aware of their gender identity since childhood.[8]
The bed nucleus of the stria terminalis has also been reported to be smaller in another sexually atypical group, pedophilic males.[9]

This ONLY suggests a neurobiological basis for gender identity, it does not prove it. As with practically every other human trait ever cataloged, for gender identity, there is a huge spectrum of possibilities, of which only a couple support the idea of a binary system of choices. For some of us, it is NOT as simple as "are you a boy or a girl". Some people identify as both, or even neither. I am happy that you have found yourself, but not all the rest of us share your binary outlook on life, hence the need for terms like transgender (which by the way, does nothing to obscure the complex nature of the topic at hand.)

Sorry, I guess that's my hot-button issue. I will quietly skulk back into the corner and resume lurking.
