Upset and angry?

     People have to be "outraged, upset and angry" and behaving in an outrageous manner themselves, to be on the news these days. The more violent and over-the-top, apparently the "better TV."
     Mimicking Hollywood shoot-em-ups, the aggrieved captured on video feel not only justified, but apparently feel a duty to enthusiastically avenge some perceived injustice - to defend their honor (bruised ego) with butchery and mayhem.
     Every nation, ethnic group and religion (even peace activists!) contains violence-prone uneducated rabble, easily triggered to react like reptiles. It's their low stage of development, and does not represent the larger society to which they belong. We have such groups in North America as well.
     A very serious human problem is projecting evil onto others in order to help deny our own imperfection. Regardless of the difficulty of the situation, reptilian reactivity escalates and prolongs problems, whereas "grandmotherly love" invariably works in the long run: http://mindfulnessforeveryone.blogspot.ca/2012/09/188-grandmotherly-love-like-oxygen.html
