A similar dynamic is at work in 2009. When pundits weave a small number of unrelated incidents into a "pattern" of crime, then link it to the rhetoric of Obama's opponents, it becomes easier to marginalize nonviolent, noncriminal critics on the right, just as a red scare makes it easier to marginalize nonviolent, noncriminal figures on the left.
THE TOWN HALLS of August. “That’s the full list of documented violence from the August meetings. In more than 400 events: one slap, one shove, three punches, two signs grabbed, one self-inflicted vandalism incident by a liberal, one unsolved vandalism incident, and one serious assault. Despite the left’s insistence on the essentially barbaric nature of Obamacare critics, the video, photographic, and police report evidence is fairly clear in showing that 7 of the 10 incidents were perpetrated by Obama supporters and union members on Obama critics.”
