Armed and Ludicrous
If you have children and they learned of the rampage in Aurora, what do you tell them if they look at you and ask "How can you protect us from this?"
The common answer would be that it's God will that they die in a theatre at the hands of a man who'd previously led a quiet life and there's nothing they can do about it except pray that their friends get shot instead of them.
Or you could tell them that you'll stand armed guard over them for the rest of their lives. No matter where they go or what they do, to the bathroom, to the mall, to the drive-in with Mary Lou, you'll be there with your Glock at the ready. This should make you very popular with your kids.
The reasonable answer, the one that says you honestly care about the fate of your children, would be "Yes, kids, there are too many guns in this country and too many unstable people who own them. The Second Amendment clearly states that a person must be part of a regulated militia before they can own a gun, so if we enforce that amendment to the letter we can reduce the number of available guns quite dramatically. This will require a new amendment, one that clarifies the intent of the first, as the interpretation of the current version has been bought and paid for by the NRA, and they care much more about their political power in Washington than in the death of innocents like yourselves."
