I think the CoC was badly structured and agree that Monica isn't at fault, for context. I think that it was quite appropriate to fire some other moderators though, like the one for the Christianity SE who point blank refused to gender people correctly.

I know a lot of nonbinary people — many use neopronouns but they are all reasonable people. I don't know anyone who wouldn't also be ok with they/them.

GNC is not the same as trans, but the high numbers do suggest a much greater number of people are happier outside strict gender roles. It wouldn't be too much of an extension to say that this may apply to the pronouns they are happiest with as well.
