Concerned Citizen: You're going to say that Maxine Waters calling for "confrontation" is a call for violence? That Holder's figurative comment that "when they go low, we kick them" is a call for violence? That Clinton's comment regarding the appropriate time for civility is a call for violence?
You're obviously not a serious person. The only real "call for violence" in your list was an over-the-top statement in 2011 by a Democratic congressman who has been out of politics for 7 years, but you ignore the President's daily ridiculous comments, including just this past week praising a current Republican congressman for assaulting a reporter.

Scalia: Representative Steve Scalise and others were shot by a left-winger. Senator Rand Paul was physically assaulted and had his ribs broken by a left-winger. GOP offices have been vandalized and conservative speakers have been prohibited from speaking at certain college campuses. Left-wingers riot when conservatives come to speak. So, though you may be technically correct that the mentioned Democrats have not called for violence, the actual violence being committed is coming mainly from the Left.
I am not saying that all violence comes from the Left, it's just that the outrage here is misplaced because we don't know who sent the "bombs."
