If you think someone is a troll using the permissive social norms of a community to be unreasonable, don’t interact. That’s the proper response to a troll trying to bait, ignore. If they’re not a troll, just particular, then you’ve avoided the issue by not interacting.
No one is being forced to be here, every choice to be here is voluntary. Every interaction is voluntary, if you choose to interact with someone who upsets you, that’s your choice. If you think the rule of “don’t intentionally misgender people” is unreasonable, you can choose to not be here.
