You are full of crap. I can't say it any nicer. Meet some trans people, read a few books, and get your head out of the sand, or wherever it is. What in your career has made you qualified to speak about this?
PS Genes make us who we are. we are ALL genetic. trans people's genes made them what they are, how could it be otherwise?
No need to reply, there is no argument you could make that would be cogent, since there is no argument possible, and you are not educated enough to see it.
