If you have no preferred pronouns, just say (none) or something
This will help make people feel more comfortable in this comm and has a side effect of showing you support trans people when making comments in other communities. It will also make reactionaries seethe and make it easier for mods to purge them, and make trans people feel safer all over the fediverse.
I do like the idea of mandating including pronouns in your first post in a thread if your instance doesn’t support them, rather than an exemption
I don’t really consider requiring pronouns to be a safety measure, more of a vibes check.
Frankly considering how normalized being transphobic on main is, I like the idea of pushing people to being supportive of trans people on main.
