mocking and quoting bigots I've seen so far
:liberalism: turns to 
"you know it's hexbear when the tankie pronoun parade shows up to force pictures of pigshit in front of you!"* real quick
[*this is paraphrased, I can't remember the exact original quote]
Or "so suddenly I'm Hitler because i think people calling themselves Fae gender is dumb"
Or "why should i need to learn a new set of different pronouns for every person I meet?" (this followed two comments after "I'm literally not a transphobe, I work with plenty of trans colleagues who feel safe around me" (average lib being scratched in real time by having to acknowledge neopronouns))
.
All of these shitheads claimed to be allies when they started interacting but our brilliant pronoun tags immediately made them out themselves as the bigots they are who only pretend to be allies because it looks bad to be openly and proudly transphobic
TL;DR: 
I have a couple of name tags with my pronouns for exactly that reason.
Yeah, i'm wearing she / her pronoun tags on my handbag in spite of being a binary trans woman and mostly getting gendered correctly, i just want to normalize this out of love and respect for my nonbinary and non-passing comrades.
I always wear my trans pride pin and pronoun pin on my scrubs! Most people don't know what they mean lol, even the she/her one. But I'm sure it means a lot to the few people it does. I'm like the only trans person on staff in the hospital I'm at, I swear.
