It’s simple: If you were born with guy parts, use the guys’ bathroom. If you were born with girl parts, use the girls’ bathroom. That simplistic solution doesn’t work though. For example, some kids are born with girl parts that change into boy parts. Trans girls are girls, not boys. Anatomically, I mean, though like other kids who are Intersex (born with neither boy parts or girl parts but something of both) their anatomy is mixed. See (for example)
A sex difference in the human brain and its relation to transsexuality. by Zhou et al Nature (1995) 378:68–70. Our study is the first to show a female brain structure in genetically male transsexuals and supports the hypothesis that gender identity develops as a result of an interaction between the developing brain and sex hormones Male–to–female transsexuals have female neuron numbers in a limbic nucleus. Kruiver et al J Clin Endocrinol Metab (2000) 85:2034–2041 The present findings of somatostatin neuronal sex differences in the BSTc and its sex reversal in the transsexual brain clearly support the paradigm that in transsexuals sexual differentiation of the brain and genitals may go into opposite directions and point to a neurobiological basis of gender identity disorder. I oversimplify.. but girl brain with otherwise mostly boy body (or the reverse) captures the essence. This causes female instincts, body language, emotional response, even female sense of smell and hearing - and these in turn lead to a female gender identity. They’re girls with a particularly distressing congenital issue. They have enough on their plates without ill-informed people spreading lies about them.
