Pri: Two problems here. First, I used the term “rising tide” deliberately. There is no such tide, and if you consult law enforcement resources like NCIC and VICAP, you’ll see that that’s case. You cite recent incidents, but I note you didn’t go back very far in your research. I’d be curious to see what happens when you stretch your timeline to the 1980s, for instance.
Second, how do these incidents you cite tie back into right-wing hate speech? In other words, were all of these incidents incited by right-wing hate speech? If the connection was there, I must have missed it.
Like DJ pointed out: Nuts is nuts. The Lefties are having the same problem tying Loughner back to Beck or Limbaugh, mainly because the connection doesn’t exist.
