Guild = drama. That's just the way it is.
As someone who also raided 5+ hours a night 5+ nights a week i'd have to say thats probably adding a bit more stress with that more social family guild type thing. Going from the gramers to the casuals is usually petty frustrating if you care about progression of your character in any way.
The best thing to do is either go unguilded if you know a lot of people on your server or just turn off the drama portion of your brain and just ignore it when you see it. Some people are just drama fountains, they're easy to spot and can usually be avoided. I've found this to be useful both in-game and irl.
