== Non-binary genders == 

 This article only mentions binary transgendered folks. What about non-binary individuals? Do non-binary individuals serve only to reinforce gender and gender roles, or is there a validity to being non-binary outside of socially constructed gender roles and expressions? Would non-binary basically affirm that males and females really are completely different mentally, rather than merely physically? Does gender really exist? Are there really more genders than 2, or does this just prove that gender doesn't exist and only sex exists?
