Travel in pairs, and carry a small digital video camera to record any incident. Show the attacks via Youtube and the blogs. Place the ownership for these whackos where it belongs- the libs. Make it backfire on them.
Camera running, ask one simple question - “who’d you vote for in the last election?”
Yeah, I think this is the best answer. Carry a digital camera, record this spittle-raving morons and show the world who and what they are...and yes, ask them who they would vote for in the primaries. I’m sure the answer will be no surprise.
