Porque no los Dos?

Do it the Italian way:

no binariə

no binario or binaria or maybe binarioa or binari or binarie

but please not binarix

Jokes aside, I think the correct one should be "binaria" because it's "persona no-binaria", where "persona" being a female-gendered word still includes everybody (persono doesn't even exist).

I'm digging how Japanese is just context based. The same sentence that says "He's cool" is the same as "She's cool" and "It's cool." What changes its meaning is the context you're using it in.

But don't you dare mention the e or @ or heaven forbid the dreaded x, because accomodating identities not traditionally considered in a language's common form is "white people shit"

*por qué

Oh noooo don't tell the shitlibs or they'll start calling it no binarix XD

As a native Spanish speaker, I must tell something: that's the de facto (I think) right way to do things. Most people in my IRL environment, including myself, disprove the use of the "e" (although we don't care about the "@").

Clarification: That's IRL in my own POV only, maybe someone has a POV that is exactly the opposite. IDK
