More than 1 million nonbinary adults live in the US, study finds

[Joe Republic]

For everyday society, gender is still essentially a Venn diagram with two giant circles.  The overlap between the two circles is small but slowly growing as they drift closer together.  People in that overlap (a) are only recently learning that this label exists to help describe their identity, and (b) are coming out as such in greater numbers as the label gains mainstream acceptance.

I can personally admit that the first time I ever heard of it and truly learned what it was, my first thoughts for a while were a dismissive "huh, that’s kinda weird".  But then flashback to fifteen years ago and that was also my personal feeling towards gay people getting married.  Attitudes change.

Is there really such a thing as a gender binary? I'm not convinced. What makes a person male or female?

Their chromosomes and genatalia.

No, he said gender.
