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 did an informal poll of our irl lgbt community that has hundreds of visitors each month and determined that trans people in my area (a fairly rural area with a somewhat large city near it) are 90% socialist. the rest were largely right wing libertarians, and usually were older people transitioning later in life. only around 5% said they didnt care for politics / didnt think about it at all.
obviously this is not conclusive for trans people at large, but its a pretty big sampling
Yeah, being trans is radicalizing as hell. You get to experience how awful even (and especially) libs can be, how fake and performative the supposed allyship of some people is, you also learn the importance of community and solidarity and how kind and welcoming others can be, how much capacity for love and care humans have when their heart is in the right place. And maybe you already need a certain radicalism to come out, it always seemed like a revolutionary act to me to put on makeup and a dress when i wasn't passing at all and go out there trampling on people's ideas of how gender works. Or to take these chemicals and hack my body chemistry, get myself blasted with lasers, prepare to be cut up and put together in new ways, overthrow unlivable material conditions and replace them with better ones that actually fit my needs. What's more communist than turning your own body into the laboratory of revolution?
