What is it about your room temperature IQ John Wayne culture that's making people think shooting each other is an appropriate expression of anger?
My theory, for the little its worth, is that your "democracy" has drifted so far away from being liberal or representative that people have reached peak disenfranchisement. In the UK, we set off a flare or punch a wall or something. I don't think most people feel so alienated from society that they feel the need to resort to mass violence to send a message, we have other avenues and social safety nets.
