MoveOn wants to mobilize the world's largest nonviolence movement, calling on the 99% to teach-in itself in time for their American Spring. That's certain to sound more palatable to America's unbaptized middle-roaders, than the invitation above, invoking the reception likely awaiting protesters who plan to converge on Chicago in May. The G8 has been relocated to Camp David, but the larger NATO summit is still scheduled to warrant a two mile wide security perimeter around downtown Chicago. What does this poster communicate to you? I'm guessing the menacing image wasn't chosen at random, it says to me the unadventurous need not apply.
