Josh Marshall at Talking Points Memo, here, elaborates on the topic of right wing tendencies toward violence.

But let's be honest about what this is about. The right -- the modern American right -- has a very troubled history with political violence. The ideological pattern is clear going back at least thirty years and arguably far longer. A simple review of the 1990s, particularly 1993, 1994, culminating in many respects in the tragic 1995 bombing of the Oklahoma City Federal building in April 1995 tells the tale. Mix in the militias, the thankfully inept attempt on President Clinton's life a few months before Oklahoma City (see Francisco Duran) and it's all really not a pretty picture.
