the fact that Malkin, Drudge, WND, et. al. have to dig into the bowels of the internet speaks volumes to the fact that the right knows their rhetoric is beyond the pale. The vast majority of those examples cited were from people like you and me, posting on bulletin boards, creating gifs and jpegs, etc. What is being discussed with regard to the right at the moment is the fact that this bullshit comes from your supposed
leaders, time and time again. From explicitly calling for someones death to tacitly approving a violent comment or threat by not calling it out, the leaders and mouthpieces of the right who have the ears of millions (as you all are so fond of pointing out), i.e., Beck, Limbaugh, Fox News, Bachmann, Savage, Angle, Palin, and on and on and on, have poisoned the political debate with their violent language and imagery. The violence from the right is evil. If you can't change something through voting, you kill. There are numerous examples that I know you all know about so no point in rehashing the obvious.
There is no moral equivalency between the right and left. The right has a literal machine, from lawmakers to television to radio that speaks to millions each and every day, and they all push the same talking points. Period. So, tl;dr, Malkin's, WND, Drudge's, etc. assertions that the left is violent complete and utter bullshit.
