I'm guessing you're not very familiar with the scientific discipline of psychiatry, in which your vaunted yardsticks of measurability and falsifiability are seldom valid (oooh see what I did there!). If you're talking about microbiology or particle physics, then your definition of scientific rigour is in the right ballpark. But (unless you want to write off the whole of psychiatry and psychology as bogus pseudoscience), those rules simply don't apply to studies of the human psyche.
Given that I am an academic psychologist and have been specialising in the scientific status of psychological explanation for nearly 20 years, including teaching a course on critical analysis of diagnostic criteria for psychiatric disorder, focusing on the DSM), and that I am citing a science-oriented clinical psychologist with an extensive clinical and research background in assessing and treating gender dysphoria, and given that almost everything you have said about the DSM is demonstrably wrong, and that the lead author of the gender dysphoria chapter of the DSM5 that you seem to think validates your views does not agree with much of what you claim about gender identity, and that the arguments you have made here implying that transgender identity not being a mental disorder proves TWAW are so absurd they are Not Even Wrong and I would be shocked to find them in an essay from a first-year student - pardon me if I don't attach too much importance to your 'guesses'.
