I haven't read past the first contributor, and I could not hope to articulate a more persuasive argument than this gentleman expressed. Still, I feel compelled to weigh in at the implication that I, a 59 year old man who has not touched a gun since boy Scouts, is not considered a "responsible citizen" by the original poster. If I may ask, exactly what was it about the horror of the Colorado movie theater shootings that made me no longer a "responsible citizen," in the posters view, simply because I walk the world unarmed?
For starters, in the chance of any given day, my encountering the type of attack that took place in the Colorado theater are not less than one in a million, but more like one in a trillion. Second, in this extremely unlikely circumstance, my having a gun, and actually using it in such circumstances, would be, as the first poster suggests, far more dangerous than my being unarmed.
Here is the mark of a "responsible citizen": a person who thinks carefully and cogently about the problems this country faces and tries to contribute to public discourse and decision making accordingly. A "responsible citizen" makes an effort to make his community a better place and contributes to organizations to advance that objective. Carrying a concealed weapon is not a short cut to the high standard of becoming a "responsible citizen." Go back and read Plato's Republic.
