I got banned from a great, progressive sci-fi and fantasy writing community for several dumb reasons similar to each other, one of them being I said Wikipedia and the entire internet said "guys" and "dude" are gender-neutral. (And yes, it was a great community. Nothing's perfect though.) Also for suggesting that maybe one day we'll be progressive enough to have a dedicated non-binary pronoun instead of "they"— at the least so my novel-writing is less confusing when multiple parties are addressed. The admins claimed I was talking in "anti-trans rhetoric". Hilariously, I have trans and non-binary protagonists in my novel, and everyone there knew it. My best friend also moved from another state to become my housemate, and she is MtF trans.
