I know that the Second Amendment/national defense has no connection to the topic at hand. It was in response to Invictus, not as a response to the thread in general. Regardless, I will respond to you.
Just to clarify, the Second Amendment is a national defense asset if we're talking about a worst-case, Red Dawn-esque scenario. Are a bunch of good old boys with deer rifles going to stop terrorists and other violently anti-American ne'er-do-wells? Of course not. Are a bunch of good old boys with deer rifles going to make life miserable for an occupying army? Of course.
One could reasonably point to defense spending and say that America will never be invaded, which would be a fair assertion. But once gun rights are gone, they don't easily come back. What if you repealed the Second Amendment, cut defense budgets by 90%, banned nuclear weapons worldwide, and waited 50 years? Now we have Red Chinese paratroopers dropping everywhere and no way to repel them. "Oh, shit. Looks like we shouldn't have repealed the Second Amendment."
Is my above scenario a little extreme/absurd? Of course. But what's much less extreme/absurd is a revolt against an out-of-control federal government. Beyond a certain threshold, armed revolt is the only way to stop a police state.

"Gunfighter seems to translate the word militia to mean populace. That job kind of falls to the National Guard as is, and they're better armed than the populace."
The Supreme Court has interpreted the Second Amendment to protect the right of the *populace* to keep and possess firearms for traditionally lawful purposes, such as defending one's home against intrusion.
