I'd like to see a source for this evidence please.

I haven't gone over these properly, so I can't actually argue for their validity, but Wikipedia claims that there are numerous studies which seem to argue the same things - https://en.wikipedia.org/wiki/Causes_of_transsexualism#Brain_structure https://en.wikipedia.org/wiki/Causes_of_transsexualism#Brain...

  The first study they cite[0] has a sample size of 6, that is not nearly enough to account for the claims they are making. The same with the 2000 study[1]. The 2009 study[2] has 24 subjects so it's slightly more authoritative but points to an entirely different part of the brain as a marker for transgenderism, it's results have yet to be replicated. I'm failing to find 'plenty of evidence' here. What sources made you come to that conclusion yourself?

    There is enough evidence for it to not be obviously false that, at the least, there's a significant structural difference between cis people's brains and transsexual people's brains, and some of those differences may fall along sexual differentiation lines. More research must be done! In any case, it's actually more-or-less irrelevant in arguing whether a trans person is actually the gender they identify as, and is mostly a curiosity until it leads to more focused treatment. The bit that does matter is the last question - am I who I am in my head, or am I who you think I am?

        Nice article. Unfortunately articles are not data. It mentions a 2013 study but yet again with a peer group of 32 that is much too small to tell you anything, and gives no further information. That 2013 I can't seem to find, but the p value if the article is correct on sample size would also be quite low, though slightly higher than the previously mentioned studies. If the difference is so clear in an MRI why not run a simple blinded study where researchers look at brain scans and tell you who is transgender and who is not? Such a study would not only prove this theory outright, but would likely make a researcher's career.

      I'm sorry, your point is that you think, so therefore reality is so? You can't think yourself into a different sex, I understand that they do see themselves as male or female despite their physical characteristics, but that has no bearing on much whether we like it or not. And to answer your question, you are your configuration of you, whether anyone perceives it or not, including yourself. I guess it's turning a bit philosophical cause I'm sure you're going to come back and say the world is only what is perceived of it, but that's not what I believe.
