I still think that you are mistaken, and that your conclusions are dangerous. The fatal flaw is that it justifies the argument of the intolerant conservatives that our identity is changeable. My background is in the hard sciences (3 medical degrees). Personally, I have certain genetic “abnormalities“ where certain of my genes are structurally the same as cis females controlling the expression of sex related hormones. I have always had problems with the mushiness of sociologists. Yes, there is societal indoctrination going on. Many of us who are transgender took a while to realize our true identities precisely because we were forced into a male form of socialization and it took us a while to figure it out. We are going to have to agree to disagree on this.
