Moms Demand Action is a bit over zealous in demanding increased gun control legislation, true, but in this context, the picture looks like an NRA campaign ad. Recently a number of local and state school authority boards have banned classic fairy tales like "Little Red Ridinghood" for being too violent. Sort of the P.C. version of fundie book burnin's.
Added later; The more I think about this sample of dumb protest sign, the more I am fascinated by it. A right wing gun nut will love it (if they don't know the organization that made it), and a left wing anti-gun nut will love it, too. It's a litmus test for extremes on each side of the issue of guns and kid's books. The extreme left hates Grimm's violent fairy tales and guns, the right hates fairy tales that aren't about jeebuz and thinks gun control is banning guns.
Brilliant of you to put this example in the thread, Shep!
