@jeffowski Interestingly, the latest evidence from neuroscience suggests (ironically) that gender identity may well be "innate" to a significant extent. Brains and primary sex characteristics develop along separate genomic pathways, and scans of trans people both before and after HRT consistently reveal them to have neuroanatomy matching their gender identity, not their natal sex.
To put it bluntly, gender - while expression varies - may be about as much of a "choice" as sexual orientation. 🤷♂️
