The gun control tribe has the momentary advantage of shock. I suspect it will go on and on, like Israel-Palestine, or Northern Ireland, or the Balkans, until there comes some changing of the cultural tide, a force that will overwhelm mere arguments over policy. That is what happened, of course, in the case of cigarettes. When I was a child, nothing was more glamorous than smoking. In fact, there was something vaguely wrong with you if you did not smoke.
Guns possess a similar seductive glamour, especially to children.
Guns were the things that heroes carried, transformative instruments that giants used to save the world from Hitler and lesser bad guys. Guns are seductive. Guns seduce children, and men as well. Of course, guns and cars have different purposes. Pending the cultural sea change, I have a modest proposal.
