You may have noted that I don't refer to myself as a woman or a girl in this blog but instead as a trans person. Sure, my instincts were there from a very young age and part of the reason for my successful social transition I credit to those natural impulses.However I am not concerned with gender norms any longer and whatever tropes work for others won't easily work for me.
My study of gender has concluded that much of it is rooted in socialization but there is defintely a genetic component which makes us predisposed to being trans. If you tried to socialize someone into another gender role who isn't trans (and here I am reminded of the late David Reimer) you will not succeed in your efforts. John Money was quite certain of it until he failed.
Our backgrounds and experiences are so varied and yet there is such commonality.
