I've seen some heated debates around in these forums (overall), as well as the troll spams, of course, but by and large, Beth fora has a pretty "calm" atmosphere, I'll agree. Considering how "large" they are/how many people frequent them.
No huge fora is going to be perfectly peaceful all the time, but all you have to do is go to a place like, say, battle.net forums and you'll know the difference.
