We never used to get such comments here. Still can't understand the mentality of such people.
Read an interesting article yesterday that I think might appeal to you also, though I'm a bit hesitant, because while it's mostly science-based, there are a few comments, mostly scattered towards the end, that some people might take political offense at. Those comments aren't drastic or nasty, but more asides, but it doesn't always take much to upset some folks nowadays. I can only urge anyone reading it to focus on the science part. I do think it's a good read re: psychology & behavior.
It's actually a review of 3 books, two written by scientists and one by a psychologist, that illustrate & explain some of the ways that our brains & psychology work. And it **might** help explain, if just a little, why some people behave the way that they do, for example trolls.
Based on the article, *My understanding*, which as always could be wrong, is that the trolls do not understand, nor do they want to learn &/or understand the consequences of their behavior, so to them there's no reason not to be a troll. At the same time they actually get a physical rush by being part of a group of like-minded people, in your example people who disliked &/or despised your clan. In real life I suspect many trolls are not as offensive, because there they see more of the consequences of their behavior, but online, they don't see any downsides whatsoever, but only the rush from belonging.
