It’s worth noting that a trans person is just someone whose gender identity doesn’t match the identity they were assigned at birth. Not all trans people have gone through (or plan to go through) any kind of medical ‘transitioning’ or ‘sex change’ procedure.
Yup I’m obviously not talking about the full range of trans experiences here, but most of the people I’ve heard anecdotes so far have done some kind of medical decision (usually hormonal therapy) because of gender dystopia. I was just saying that in general trans people would be the ones who would understand the physical/biological mechanics of gender in its full capacity.
