And that's what's so odd about their bias in general. The Left has shown, again and again, that they have a taste for violence - and yet, they're forgiven. The MSM crew has absolutely no fear of them, regardless of how violent they really are.
But the Tea Party? Regardless of how violent it isn't - heck, they even clean up after themselves when protesting - the MSM and liberals show a clear pattern of fear. A calm and rational non-conservative would write off the spirited rhetoric as people just sounding off, given that the strong words do not lead to any violent incidents.
You've latched on to something, all right. They know what they do, and they fear payback. Else, they're just exhibiting the kind of paranoia that springs from a guilty conscience.
Fear the wrath of the patient man.
