You know the ones, the exploders – at the first hint of trouble, be it someone in the wrong place or someone asking a question on Vent at the wrong time, they’re the first ones to let their tempers flare. They’re quick with a “if you’re doing ________, you’re doing it wrong,” and they’ll snap at anyone who tries to calm them down. They may be raid leaders, they may be members, they may be officers. Maybe you’re a raid leader with one of these folks in your raid. Maybe you’re just a regular raider, in a position where you just have to suck it up and hope it’s not you they’re yelling at. Maybe it’s you.
How do you (or your raid group) deal with hot-tempered folks in raids? Sure, in progression, there’s bound to be some level of irritation as your raid throws themselves against bosses and endures huge repair bills, but I’m talking about those people who’re blowing up every week on any person for the tiniest thing wrong, even when it doesn’t affect what you’re doing because hey, you’ve got this boss on farm. The ones who raise their voices over trivial matters, and who – heaven forbid – can never be corrected on anything.
Stop used to be a warlock, then he was a death knight; first he was Horde, then he was Alliance again, and now he's Horde again. For good this time. Lok'tar ogar! 
Really, if the person isn’t willing to control themselves whether it’s through exploding, lootwhoring, going afk all the time, whatever, they usually do not get asked back again and usually are removed from the raid if not the guild.
I myself am prone to being an “exploder”; add to that the sleep deprivation of having a newborn child and I’m a time bomb waiting to go off. However, I try to control myself. Instead of ranting or talking behind someone’s back, I will just breath and realize that maybe I need to take a step back. If things get too bad, I will sit out of a raid or let people know I will do one or two more attempts before leaving. Then after a couple of days I will either post something on the forums explaining my frustration, trying to make sure I don’t single someone out. Usually we get some kind of resolution, and other times we don’t.

Unless it’s a raid leader or something, in which case I politely message them that I do not appreciate being yelled at, or listening to my friends get yelled at. This is a game played for fun, and that’s the focus of our guild.
I’ve actually not signed up for raids because I didn’t want to deal with people like this. While I love downing bosses, it’s not worth dealing with abuse.
I complain in the DK channel to my fellow undead folk. The raid leaders know about the problem and it seems to have gotten better in the last few weeks, so hopefully the temper is now under control.
