I promise I am not a reactionary, but I am somewhat uneducated on the subject so I might say something offensive accidentally, sorry in advance about that.
So, does gender dysphoria stem from a disconnect between the body and some "gender socialization" function of the brain, which could be solved by getting socialized and treated by everyone as the correct gender from the start, or something that stems from a disconnect between the brain and the actual body parts and hormones, so the transition is needed to alleviate that, or both?
I think there's a strong connection between the gender society treats me and the gender I am. For me they're close to being the same thing.
