I suppose all the old-times here have already read this but in my explorations down the rabbit hole I came across the following article, and this passage put into words the things my non-scientific brain could not:
Let me just say that I don’t believe that anyone on Earth is “transgender,” “transsexual,” trans-anything except perhaps transvestite, because that term is specific to clothes (Latin vestīre). In English the word just means crossdresser, which is accurate in a simplistic way. Nor is anyone “cis.” Evolution would not allow development of a heritable trait cluster or quasi-sub-species in which a woman or man in good physical health would have an insatiable obsessed yearning to mimic the sociocultural sex stereotypes (i.e. “gender”) for appearance and mannerisms of the opposite sex. There is no way that little Johnny likes to play with dolls or that little Jenny likes to play with trucks because as “trans kids,” they are on the spear point of an ancient evolutionary process that manifests at a certain prevalence in a given population. Had there been such genetic innovation back when we roamed the savannahs, folks with those characteristics would have all died out pretty quickly due to the lack of skilled plastic surgeons and endocrinologists.
