Ummm, with an almost insignificant change of circumstances, attacking a guy with a rifle could be an act of heroism. The guy who rushes an armed shooter and saves lives would be viewed in a very different light.

All your responses about gun matters focus heavily on the right to self-defense. I don't think this is a central concern with firearm ownership; yes it does happen but most statistics on its frequency are muddled by the RKBA crowd determined to push their arguments, and being able to purchase assault rifles from vending machines in airports is more important to them than any honest discussion. The same people who say Stalin killed a hundred million people say that guns are used in a hundred thousand acts of defense every year.

It's like the old argument about having the runaway train kill one person or six people; I don't say this of you, you strike me as reasonable, but the strident arguments about self-defense show a fascination with helplessness only mirrored by the S&M bondage crowd. Right now gun ownership in the USA is simply doing too much harm, not only the mass shootings but the fanaticism and rage.
