[Still Thinking]

On the other hand, there’s no way of denying that the right to bear arms (i.e.: a pistol or revolver) brings its own grave dangers with it, think of the tragedies that happened at U.S. high schools in recent years. They surely are linked to that right to bear arms.

If that's true, explain why the most gun-rights friendly jurisdictions in the US are also the ones with lower crime rates? And why when these massacres take place even in geographical areas friendly to guns, is it always in a school, church or other area where the shooter expects others to be unarmed? Why are the English even now moving to control the sale of knives if guns are so inherently dangerous in the hands of ordinary citizens?

Your post deserves a special answer, although I am addressing all, in fact. It makes eminent sense, what you are writing here. It's always nice when a person learns to see from a different perspective, even if he doesn't make it his or her own immediately. It is very true that just in London City, some 18 teenagers were killed this year with a knife. In fact, we have tragically gotten used to the BBC morning news carrying another sad news item about such murders. So the focus shouldn't really be on the kind of weapon used. Guns and knives are in themselves a-moral (as opposed to immoral). The morality is in the person using them, and the goal for which he or she uses them.
