I personally think that "non-binary" is a ridiculous concept that doesn't exist and people who feel neither man nor woman have other, unidentified issues going on. Mother nature, in every species of mammal and many other animals besides, assigns us a gender. There is no middle ground and there never has been. That you can be assigned the [i]wrong[/i] gender is something I'm willing to accept, but rejecting both male and female is just silly.
