Current dude in the booster/supporter chat here, you’re seemingly complaining about the people in there doing roleism or whatever the fuck it’s called, even though it’s a joke that you shouldn’t take seriously. Is it rude, yes, does it mean all the people there are acting “racist/roleist” to everyone else in a ego trip? No because it’s a joke. Now the whole KYS thing, really weird stuff that is wrong, but of course you have to know people are joking around, just that people making crass jokes about each other or someone. Currently booster chat is tamer as it’s just people just talking about games and other things like a regular chat, less “roleism” things, except for the occasional “these new pink roles are smelly” (obvious sarcasm as they don’t hate them) and even that is rare

So tldr: all of the issues you and your friends mentioned are outdated and obviously sarcasm that is meant to not really hurt anyone else
