Street Epistemology: Is sex binary?

This is a facebook discussion about the “controversial” topic of gender theory in academia and society;  between the idea that sex could exist on a spectrum, or that it is binary. I decided to engage in this topic to better understand my own position and challenge someone else’s belief that it is binary. I was able to shed my antiquated beliefs and I hope that my interlocutor could in the future shed theirs also. TRANS RIGHTS!
