The reason we stand in arms and complain about images like the ones in the video, is very simple. Living in the most advance/ powerful nation in the world has disrupted our animal instincts. The scenes in that video are a daily occurrence, just like suicide bombings, massacres, genocide, and the list goes on. In other countries a kid by the age of 5 would have seen more gore, than you can find in the internet. So, to those who are crying about this, learn that even our own God (Jews & Christian) was at one point a violent war inducing God.... Which means, we have always enjoy the thrill of war and as long as mankind is around, war and genocide will drive our most primal thoughts and actions.
