I can't help thinking this sort of thing is a result of a combination of learning how to think being replaced with learning what to think, and regarding people who think differently as being inherently inferior. After all, what I think must be right (or I wouldn't think it) and therefore if someone else thinks something different they must be wrong. But because I can't explain why I think the way I do (not least because I don't know, other than that I've always been told it's right) it's impossible to have a rational discussion, other than to point out that I think the way I do because it's so obvious to any right-thinking person and therefore anyone with a differing viewpoint must be so oblivious to reality they can't see what's obvious. From there it's not such a big step to assume that people apparently so oblivious to reality they can't see what's obvious to me must therefore be actively trying to harm the perfect society and therefore people who must be stopped. Throw in the increasing sense that each of us is nothing more than a number in someone's computer system, and that the system isn't listening (whatever system we're talking about here, whether it be what's laughably called the IRS helpline or the customer services department of any major organisation that invites you to spend 58 minutes on hold before connecting you via a really bad line to someone who can't actually help you other than to read the script) and it's easy to see why people get angry. The people who never learned to express emotions normally have no way to handle their growing frustration and anger, and sooner or later they'll take it out on people who they see as being the problem. Rich against poor, black against white, old against young, men against women, Jews against Gentiles, the powers that be have played the divide-and-conquer game for so long it's a wonder any of us can get along.
