THEY SAY: "We'd be better off if no one had guns."
WE SAY: "You can never succeed at that, criminals will always get guns." (FLAW: The implication here is that if you COULD succeed, it would be a reasonable plan.)
WE SHOULD SAY: "So, you want to institute a system where the weak and elderly are at the mercy of the strong, the lone are at the mercy of the gang. You want to give violent criminals a government guarantee that citizens are disarmed. Sorry, that's unacceptable. Better that we should require every citizen to carry a gun."
