I have not been on an official tilde server (I wouldnt join because they have a code of conduct which I think infantilises adult humans)... but I am on a few pubnixes (circumlunar.space, rawtext.club, colorfield.space) and know a large number of folks that do not align with social and economic left values on these servers. Honestly, most of us stay out of political discussion on the servers and mostly talk about tech or sometimes philosophy (which can have political elements to it). Anecdotal, of course, so ymmv... but so long as you arent being a jerk to other people I've not seen any issues with people having diverging views of those sorts on these servers (at least the ones I have been on).
