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 would not have assumed you're a rude asshole based on the rest of your comment -- but either way, thank you for being friendly.
I don't like (any) as that means I acquiesce to the years of being assumed male by default on the Internet. I feel spite about that not because I feel euphoric when she/her'd but rather at a more base level of feminism -- that male-by-default is a patriarchal practice and so I object to it. If I were ok with (any) then I'd be OK with he/him. As a cis woman, he/him doesn't cause me dysphoria, it just causes me to roll my eyes at the state of the world. Making my pronouns visible isn't a fix for this, it's just a band-aid as it doesn't magically cause the world to be less sexist. Honestly, getting he/him'd by default is basically a useful litmus test for the state of sexism in a community I guess.
I'm not interested in changing my pronouns to a neopronoun or to any other pronoun really, but it's a nice suggestion and the aside about the mathematician is really interesting. As a mathematician myself I approve of the etymology. :)
