Evidence shows that it is not as inherent and built-in from birth as many people think, but is better characterised as a self-belief that can change over time.
Detransitioners are probably the best-known example. There are others, like males with autogynephilia who eventually end up believing they are women, sometimes even in middle-age or later. Also, there are medical case reports about transsexuals with dementia forgetting they identify as the opposite sex, and being shocked and horrified at what has been done to their body. As well as that, there are the "gender-fluid" people whose identity fluctuates rapidly rather than being fixed.

I have a lot of evidence in front of me that shows the opposite. What are you reading to lead you to the opposite conclusion?

Transgenderism is incredibly rare in populations: .1% to .6% of the population. Of that, detransitioners are also incredibly rare: about 1%, and it's not clear yet what percentage of those stop taking puberty blockers or hormones because of financial reasons. Doesn't exactly make the case...

Correct, because gender is indeed a spectrum. Again that just seems to be making my case for me...
