There are of course also people whose identity is non-binary, whose experience may be more difficult for cis people to understand, but are a better example of a gender identity that is not easily relatable to sex characteristics.

I found learning about fa’afafine was helpful to show where gender identities from my (Anglo) background did not adequately describe a material situation that is uncontroversial in its own cuktire.

What you're describing just sounds like any other subculture. Can you define what a gender is not? As in, why are "goth" or "emo" not a gender, by your definition of gender?

At least as far as I know, non-binary identities are still anchored to the male-female dimension (which correlates to sex), but in a, well, non-binary way (i.e. a mix or complete rejection). From quickly looking them up the fa’afafine seem to line up with that.
