I don't think anyone has written about this yet, and I'm certainly not a good enough writer to share an extended opinion. It's definitely an interesting read.
Many of us probably get our core gender identities as much from our biological origins as we do from our gender educations.
I keep running into smart people who seem to think I believe that sex "isn't real" because it is all "socially constructed." Allow me to correct this erroneous social construction of me by summarizing here what I think about sex and gender. I'm tempted to say "what I know about sex and gender" because there are few things I feel as sure about as this.
