Proponents of civilian disarmament know exactly where to draw the line when it comes to deciding which guns Americans should not be allowed to own: any gun that scares them. The gun control advocates I mean. And if you’ve played that game with them you’ll have heard the rhetorical technique known as reductio ad absurdum. Specifically, “should Americans be allowed to own nukes?” Most gun rights advocates draw the line at weapons of mass destruction. Gun control folk respond by insisting that a black semi-automatic modern sporting home defense rifle is a weapon of mass destruction. Anyway, where do you draw the line? Should you be able to buy a Russian ZU-23-2 AA gun or similar? Without a background check or a permit?
