Besides sanitizing the party affiliations of scandal-ridden Democratic politicians, one of the more blatant examples of media bias we regularly see is how the usually disturbed people who turn out for left-wing protests are routinely portrayed as normal.
There's no better way of observing this disparity than seeing uncensored reports of what lefty protests are actually like. And there's no better chronicler of these events than the anonymous blogger Zombie. You'll get a real flavor (and several laughs) of left-wing lunacy by checking out her latest report on the fifth year anniversary of the Iraq war in San Francisco.
After reading Zombie's photo essay, head over to the San Francisco Chronicle's "mainstreamed" version of the event which doesn't mention any of the communist groups, pro-terrorist factions, and violent jerks who constituted the majority of the protestors.
