It's impossible for a reasonable, sensible person to imagine the racism and hate of liberal/progressives who insist that "white guys" be blamed for a mass murder, when the skin color of the perpetrator is without relevance. Conservatives just want killers caught and punished, but liberals insist on introducing their racism into the consideration of guilt and the capture of criminals.
The killers in Oklahoma City, Littleton, Aurora and Newtown were found to be white, but conservatives still wanted them to be punished severely regardless of skin color. Before the guilty parties were determined and caught, I heard no conservative make a statement of what he or she preferred to be the race or ethnicity of the actual culprit(s). We just want them caught and removed from society. But liberals are not so broad minded.
So while the liberal press seem uninterested in black-on-black crimes (as is the extreme case in Obama's Chicago) they are quick to point their racist fingers at the white population (and specifically conservative whites, as happened in the Aurora shooting in which a reporter quickly, and inaccurately, blamed the TEA party for the crime) for headline-getting crimes in an attempt to achieve some of their beloved "diversity". But the facts just don't support their racist rhetoric.
The liberal media should have their second amendment rights denied them if they can't just report the news and not report opinion, and we need to insist that they also report all the news, not just the news that favors their preferred side of the issue.
