Case studies like David Reimer are pretty definitive, in my opinion.

The David Reimer case is not really "evidence" of anything. At best it's more like a hint or a suggestion. "Evidence" should mean there is a scientific theory and someone conducted an experiment to prove or disprove it and, hey, look at the evidence, it tells us something about the theory. The Reimer case was a complete destruction of a person's life, but it was not perpetrated as an experiment of any kind. Although if I remember correctly the perpetrator did claim he was testing a theory, the unethical and haphazard, disorganised way in which he went about it completely discredits any pretense to science.

So, other, actual evidence, please? A citation in a journal would do. E.g. Yu & Yu 2017 "Gender identity has a biological component" or something of the sort. Something we can accept is "evidence" in a mainstream, standard sense, not in the sense given to "evidence" by the internet, like "I know of something that agrees with my personal beliefs so it's evidence that I'm right".
