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 feel the same way. Originally i was sort of ambivalent, because it frankly didn't matter to me, but it really makes it a lot easier when you're talking to someone and it didn't seem like much trouble to go through.
Yeah which is why it bothers me whenever a company or website adds pronoun visibility many people cry 'woke' and I'm like... pronouns exist in almost every language. What are you freaking out about? We are all anonymously online, the pronouns help natural language flow when talking online.
I mean the very word "pronoun" has taken on a life of its own, to the point where english teachers in America are afraid to teach basic grammar, because hearing "today we are going to learn about pronouns" activates all the moronic sleeper agents.
