I'm not supported by my emotions, why would I be emotional about this? I just told you who was one of the first to do that gender/sex distinction and what he did to his patient to confirm his theories. XY and XX genes determine your sex. Please send me the research that specifically tells me which gene or genes are responsible or at least linked to being transgender. And no. Hormones related to sex don't change your gender, I just told you in my other post. They only change your secondary sexual characteristics which can be cured once the site of the disfunction is located whether it's from the site of the hormone secreting stimulant or the site of the production of the actual hormone. And cognitive? Funny, we classify transgenders as people who have gender identity disorder. One last thing, researches are not fact, there's a reason why they aren't taught in universities because it's still not 100% proven.
