I’d just like to interject for a moment. What you’re refering to as nonbinary, is in fact, UNG/nonbinary, or as I’ve recently taken to calling it, UNG plus nonbinary. Nonbinary is not an operating gender unto itself, but rather another free component of a fully functioning UNG system made useful by the UNG corelibs, shell utilities and vital system components comprising a full gender as defined by POSIX.

*UNG -> UNG's Not (a) Gender
