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: 
NGL I was mildly against the pronoun thing when it started, but I was humble enough not to get involved in the struggle sessions. So literally thanks to Hexbear posters for putting me on the right side of history.
I had a moment of "I'm not sure I want to be obviously female on the internet," then I remembered I chose a feminine username and realized I was being real dumb. Also it's Hexbear, so misogyny just isn't a problem anyway.
My stance on the pronouns was always:
Seemed like a pretty easy choice
It makes some people that are comrades happy and takes basically no effort to just have them there.
As a bonus it makes chuds mad.
I wasn't really against it, but I didn't set my pronouns at first because I didn't think I should call attention to myself as a cis guy, but TC69 wrote an effort post mentioning that people like me setting pronouns normalizes pronouns. So I did and pronouns are good. It's nice to know how to refer to people.
