Pri: I would never debate nor deny that the Right does a better job of it. As I pointed out earlier, their listenership/viewership dwarfs that of the Left.
However, as to your point regarding a concerted, long-term message of violence: You’re obviously referring to the rising tide of assassinations, murder attempts and violence against political figures, correct? You see the problem, here, right? That simply isn’t the case, and we both know it. The Gifford shooting, while tragic, is NOT part of some larger and more dangerous series of attacks, nor is it “collateral damage” from these supposedly stage-managed and “engineered” programs from the Right.
The fact that the Right is more successful than the Left and enjoys a wider audience detracts not at all from the fact the both sides engage in the same vitriolic spew and do it for considered effect.
