I've been waiting until after Christmas day to make this post, but some of our communities recently have had a lot of noise and upset over someone that uses neopronouns that most people are unfamiliar with.
So I want to make this clear. A persons pronouns are to be respected. This is true when the user is using neopronouns that you're unfamiliar with. It's true even if you think someone is trolling. Pronouns are not rewards for good behaviour. They aren't only to be respected when you like the person you're interacting with, or if their pronouns "make sense" to you. Trolls, spammers, twitter users, it doesn't matter who they are, your options are to respect their pronouns, or to not engage with them.
I really want to re-iterate the importance of this. Gender diverse folk are undermined, invalidated and questioned at every step of our lives. As a community, we need to be working to undo that, not creating more of it, and that means there is no space for treating pronouns (including neopronouns) as a reward for good behaviour.
This isn't a free reign for trolls and spammers. The rules still apply. Trolling, spamming, etc will continue to be dealt with, but it's not an excuse to act as if respecting someones pronouns is optional.
I see that case as an anomalous one because the tension I personally have there is: a person may be a god, but that doesn't make that person my god, and I shouldn't be required to behave worshipfully towards a god I don't follow. I may choose to follow other religions' conventions around how they refer to their gods and/or prophets in some contexts, but the idea of not having a choice in matters of religion makes me deeply uncomfortable. Respect between equals, which is what using a person's pronouns generally is, should be automatic, but deference to authority should be earned in my book.
I don't think using someone's preferred pronoun capitalisation is a worship thing. On My antirealist discord server, capitalised pronouns are the default. If you want lowercase pronouns, you have to pick a role that says so.
I've met people who thought capitalised pronouns were a matter of religion. But I've also met people who think "he" and "she" pronouns are a matter of religion. They think their gender identities are handed down to them by Elohim, and refusing to use someone's god-given pronouns is a form of disrespect against their god. They say "My god doesn't make mistakes", and think their religious beliefs are a reason to misgender people. I think that if treating people decently means decoupling pronouns from religion, then everyone should decouple pronouns from religion.
