Please my dear readers do not believe the hype, not for one second. For although you may see some violence on facebook and youtube, the violence in America does not really stem from the left nor the right, these are just purely small incidents happening in a few small campuses scattered around the US. IF you are really interested in who is committing violence in America look up illegal immigrant crime rates in America.
