For what it's worth, I've seen a lot of people get confused between "nonbinary" and "gender nonconforming", as well as people who casually call themselves "nonbinary" for clout, acceptance, or because they were bullied into it.

I used to refer to myself as "genderqueer" - what "nonbinary" used to be called when it first started being a thing - because I was told that it meant a gender nonconforming person. Fortunately someone corrected me pretty quick, but still. "Nonbinary" is a ridiculous concept because it's impossible for humans to be neither sex, so I think many of us first thought it had to do with gender roles at first.

Anyway, my point is, just because someone calls themself nonbinary doesn't necessarily mean they're a Kool-Aid drinking moron - they may just be mistaken or it may be something they were heavily pressured into. In my experience especially, "nonbinary" people don't seem to keep that label for very long.
