Funnily enough I got insulted by the main tank on Ifrit hard last night! He started insulting people when they died and I asked him to stop, pointing out that it's not going to help anyone - which once we won made me public enemy #1 of course and I got a tirade about being a crap player and all that even though *I* had to scrape *him* up off the floor at the end XD

That's not acceptable. But what's also not acceptable is the total silence from everyone else. Everyone who keeps quiet when someone goes off on a rant for no reason is giving these people permission to behave like morons - maybe you don't mind, or maybe it's not directed at you - but the next time they do it they might be attacking someone who does, and that means we end up with one more bully in the DF queue and one less enthusiastic learner.
