If we are to be truthful (!) the anti-gun Left is idealogically driven, therefore logical or factual arguments do not persuade them. The goal is destruction of the 2nd Amendment and disarmament of the people. Therefore, "gun-free zones" must be maintained in order to invite invasion by loonies who desire to commit atrocities against the helpless. These atrocities are then the springboard from which to attack the 2nd Amendment and law-abiding gun owners. Why else vehemently oppose armed security for "the children" in the wake of something like Sandy Hook? Alas! apparently there were insufficient ballpoint pens available to take out Adam Lanza.
