Just wanted to add I found this quote on twitter about non-binary:

Being non-binary is an ideological trap. You reject the strict rigidity of gender binarism—I’m with you there. But you define yourself as a negation. Your identity, then, existentially depends on this binary.

You are not dismantling it, you are immortalising it.

Someone tries to throw in an atheist analogy so the commenter replies:

Being non binary is the sum total of these people’s identity. They define themselves by not subscribing to the binary—but they have to always think about what the binary is to successively avoid it. And others need to think of it too in order to make sense of what being NB is.
