Some are made to kill people very effeciently, yes, but, properly employed they can all kill effeciently. As can a pickup truck or bulldozer.
I understand your viewpoint and sense the circular argument coming, but I always feel that we are ceding the field to the antis- when we claim some guns are more intrinsically violent or evil than others.
