My DUmmie trolls are strictly in the business of psychological enlightenment. Their job is to make DUmmies wonder why their sick ideology cannot withstand a second opinion. Why walls, which "do not work" in their official script, must be built, utilized, and constantly reinforced around their group-think to protect their "truth".
It is a subtle walk across a brilliantly strung tightrope. They have no idea about the actual outside forces they must battle in order to stay miserable and insane. It's like Radio Free Europe for the political sheep-crazies behind the DU walls.
Hey, maybe walls don't work after all.
