Bob, you're exactly right. All the while completely ignoring the left wing crazies, like the folks at occupy wall street convicted of building bombs, the movement that needed to build rape shelters. Or the left wing crazy that tried to assassinate Giffords, or the crazy that tries to assassinate a number of LAPD folks.
Nope, its still really those bourgeois Tea Partiers who leave demonstrations areas cleaner than when they found it that are the real dangerous ones.
Its this kind of behavior that shows we are typically not dealing with genuine people. But our side still gets caught up in treating them as if they are engaging in "honest debate". One on one with a normal person, sure have an honest debate. At the higher media level, our side should be focusing on exposing them as dishonest ideologues, not trying to engage "debate" set by their ground rules, a frame of rules designed to make us fail.
