This holds merit. Like you, I know it's a way of them puffing out their chest and demonstrating how they're willing to take on "evil." It also reinforces to them that if their elected representatives were to do the same, they wouldn't get run over all their time (from their POV).
I'd like to extend the discussion further. A primitive who tells a bouncy knows it's a lie. No doubt they see this as a way to rally the troops, and they take some comfort in believing they have done so. But when they're by themselves, does it even bother them that it's a lie? Wouldn't the fact that they did it cause them to wonder if others are doing it also? If it happens often enough, and they recognize it's just a series of lies, doesn't it undermine the whole purpose of the bouncy to begin with? Or maybe they're really that self deceived.
