The number of youths now considered “transgender” is 20 to 40 times what it was a decade ago. It is highly unlikely that the genome has changed that much, so are we just redefining the meaning? More importantly, are we overtreating these youths because the definition has changed even if the underlying reality has not?
My sister was, and is, by any reasonable standard, a Tomboy. She was always happiest pursing frogs and snakes and beating my brother and I in sports. She is also spectacularly heterosexual, once breaking her foot in intercourse.
The world would be a sadder place had someone pounced on her with puberty blockers and hormones to help her be a boy.
