It's been discussed before, but before social media, most people who got a bit too wound up over something were surrounded by family, friends, co-workers, and so on who had a braking effect on them. Their circle tended to rein them in, throw some cold water on their fire, and bring them back to normal. Today, it's just the opposite. They isolate, find themselves a group on the Internet or in social media that will amplify their anger and frustration, tell them they're right and justified in feeling that way and wanting to do something crazy about it, and turn it up to 11. There's little normal social and family influence anymore dialing things down for such people. Social media usually does just the opposite.
