Well, I've seen worse, at least no one gets threatened. But it doesn't suprise me one bit. About 6 years ago I started to abandon comment sections altogether, because every second poster or so had some agenda politically, religiously or some esoteric nuthouse BS. This directly affects the quality of the other (genuineley interested) postings, because they started to argue with the trolls and shills. What once were intersting fora of conversation became snake pits. Not everywhere, but to a significant degree.
