Glenn Beck (whom I try not to talk about for fear of receiving the wrath of his imbecilic followers - yes, they scare me more than the dittoheads) is planning an event of monumental proportions that (with any luck) will be a flaming ball of self-destruction. He's planning on making a speech from the steps of the Lincoln Memorial on the anniversary of Martin Luther King, Jr.'s "I Have A Dream" speech. He's told his followers not to bring signs, but that they should bring their children.
Hmm. I'm thinking. Perhaps we should have something that looks like a child stuck on a pole, so you can get the best of both worlds?
No, truly, here's what I would propose. Get as many people as you can to surround the folks who will no doubt barely fill the steps at the Washington Mall, and laugh your asses off the entire time. Non-stop. Eerily like a bad episode of the Twilight Zone or Outer Limits, but with the appropriate effect. Laugh at him. It's what he deserves. He really is a rodeo clown, who either doesn't read the history books he promotes, or he's a rabid anti-semite. Who can cry on cue, to prove that he "really, really cares about America." Just like all the other crocodiles.
I would also recommend carrying signs that have as little meaning attributable to them as possible. One of the early Rev. Phelps counter-protest signs read "I Have A Sign", which I think is just about the right level of total absurdity. Just so long as we're not calling him names or being mean to his followers. The best way to get them to show their true colors is to be as inane as possible.
