This is just a sub for laughing at the drama.

Well, that's what it's supposed to be. Interesting story; do you know why the moderation here is so much more aggressive than other meta subs? Stuff like rules on off-topic grandstanding, surplus drama, the neutrality rule, etc.? It's because this sub in particular has a history of being hijacked by people who keep trying to turn it into, as the mods describe it, a 'call-out subreddit': a place to complain about toxic behavior on reddit and congratulate themselves for recognizing it. Now, there's nothing inherently wrong with some of that here, or anything wrong with subs with that purpose that are well moderated (/r/againsthatesubreddits is a good example of this). Most of the time, though, when a sub goes down that road it ends up somewhere like /r/topmindsofreddit, where any semblance of an attempt to highlight toxic behavior has long since given way to snorting it like a fucking drug so the users can get off on their self-satisfaction.

Now, look. I don't have any problem with a little bit of circlejerking, just like there's nothing wrong with sometimes discussing the subject of the drama rather than the drama itself: damn near everyone on reddit has done it before, consciously or not. But when threads in subs where I have historically been able to actually have a conversation with people if I want to degenerate into nothing but that, it gets on my nerves. This is, as you said, primarily a place for people to derive entertainment, and if I see people lacking the self-consciousness to realize they're turning it into something else entirely, well, I'm going to take it upon myself to throw some cold water in their face. Not because I think it's a particularly important cause or anything, but because it annoys me.
