"they/them is... about, like, feeling human at your core"
See, that is the type of shit that drives me up a wall with this whole non-binary thing: they are unable to give a clear explanation as to why they exist. They resort to vague shit like "Oh, I just see myself as a human". Hmm, maybe it's because you are a fucking human. I'm not saying people should conform to gender norms. I'm just saying that acting as though this needs to be officially, legally recognized is retarded and frustrating.
It's like those people who say "I don't see myself as an American citizen. I see myself as a world citizen". Like, okay, you can think like that, but you're still recognized legally as an American citizen. Non-binaries are the equivalent to people who want to put "world" as their place of residence. It's that level of frustrating.
