The video that says this?... 

"We're going to laser-focus on your so-called 'honest pursuit of truth.' In short, we're coming for you," Loesch said in the video. "Consider this a shot across your proverbial bow."

You take that as a threat of violence?  Seriously?

And speaking of unhinged supporters, as I pointed out elsewhere in this thread, the preponderance of violence is coming from the left, not the right, not from NRA members.
