"Stochastic terrorism"
I think Nads stumbled over that term in her Googling sometime last year and introduced it to the Hive. It was Pretentious Word Of The Month there until it was replaced by trajectory or arc or trend or whatever.
If what Santorum is saying is stochastic terrorism, what is, "It won't be long before the rich are no longer protected by their gated communities", and, "They won't be happy until we are all dead", and, "We need to start arming ourselves", and, "It would be nice if (name here) met with some kind of accident", all of which and many more such sentiments we've read over and over on DU? Most if not all of the violence we've seen attributed to the Right has been perpetrated by individuals with disturbed mental states whose politics, if any, have been muddled or even bent to the Left. That hasn't stopped DUmmies from unilaterally proclaiming them all as calculating, card-carrying conservatives despite clear evidence to the contrary. All it takes is one DUmmy proclaiming it, evidence be damned, and all the rest latch onto the meme like it's the gospel truth.
Meanwhile, there's example after example of Leftist mob violence, most recently in the form of "peaceful OWS protesters", that gets rationalized or handwaved away as "agents provocateur".
