This might be a weird question, and I want to start by saying that I ask it in good faith. I teach cishet people about how to be nice to queer folk, and this is one of the things that's the hardest for me to teach well.

That subject is "being nonbinary".

I'm definitely binary. There has never been a waver in my belief, since I was old enough to express it, that I'm a girl.

So I don't get what it feels like to be nonbinary. Which means I can't kind of explain it to cishet people either.

So I'm asking my nonbinary friends here, do you feel like you have a gender, or is it really a rejection of gender as a construct? Or both? Neither? Eighteen other things entirely?

I'm trying to come in without known biases here, but I apologise if I've mistakenly said something hurtful.

Will someone be kind enough to educate your sister, so she can educate others?
