@BillRM,
Your point is what? That case is a tragic example of a failed attempt at gender re-assignment. It is about gender identity.
Gender identity--knowing whether you are male or female--has nothing to do with culturally learned, and acquired, notions of "masculinity" and "femininity".
We teach children to recognize gender differences--i.e. a boy knows he is a boy because he has a penis.
But then we begin teaching them how boys and men are "supposed to act", how we expect them to act, what "masculinity" is--i.e. men don't cry, men are strong, men are tough, men are independent, men should be in charge and in control of things, etc. We teach children how to think and act like men, as part of socialization, just like we teach them manners, toilet training, religious beliefs.
This might be easier for you to understand if you realize that different cultures have different notions of "masculinity". Our culture has a patriarchal notion of "masculinity". In a matriarchal culture, notions of "masculinity" might be quite different.
Cultural gender roles, stereotyped expectations of appropriate gender behaviors, attitudes, etc. are learned.
Since cultures and societies undergo changes, these notions about "masculinity" (and "femininity") may also have to change or expand over time, rather than remain rigid or fixed, in order to keep them useful and not dysfunctional.
