Before I started writing my novel, I'd write shorter stories with the same characters and post them separately. In one story, a character mistakes a nonbinary character for another gender. The nonbinary character's friend tries to correct him on it, but their other friends are like "Shh, don't out them." This is one of the first scenes in the story.
I got a comment saying that I shouldn't have put that scene so early on, because (paraphrasing) "Most people aren't going to care for pronouns in the beginning of their sci-fi story." Looking back on this, I think part of it is a misunderstanding. I wrote that scene knowing it wasn't meant to be the introduction to these characters. This commenter wouldn't have known that.
I was going to defend the comment more, but looking back at what I wrote, I think it's fine. That character's pronouns weren't even the thing that was being corrected, so I don't know where that came from. Anyway, I'm probably still going to include that scene when I get to that point in my novel.
