A lot of people here have long since made up their mind about hexbear based both on repeated meta posting on the topic and possibly a bad experience or two with them on a topic they assumed was uncontested but is a landmine topic for communists of a particular bent
I’ve personally never had a bad experience with hexbears, possibly because I’m more empathetic to their perspective, but more likely because I know when it’s time to disengage. There are users on lemmy who feel strongly about a certain topic that’s abrasive to hexbear users and dig in their heels when jeered at (or maybe feel a personal responsibility to stand them down) and are usually the users here who have the most complaints, because the standard reaction from hexbear users is irreverence (both the users and the mods).
Unlike a lot of liberals coming from reddit, communists often don’t have delusions about the neutrality of moderation and so they’ll ban you on a whim if they think you’re there to stir shit. They use the ban hammer judiciously even with users on their own instance. That’s often the biggest complaint both with hexbear and with lemmy.ml.
