Dunno why you don't just make it compulsary to join the national gard to own a weapon. Its a win win win. NG gets more people, people get actual training on how to use their guns, and a third win which for some reason i can't remember 30 seconds after thinking of it. But i'm sure it was good.
That sounds like it works in theory, but believe me when I say an all-volunteer force is better. Sure it's nice if everyone has military training, but the lack of military training also creates a tactical flexibility that cannot be beat. For example, colonials adopted the Native American hit-and-run while the trained British stood in lines firing. If we were to fight like they fought, our revolution wouldn't have been successful. We would have fought like that if everyone was trained. Now look at how wars are fought. See, untrained can be of great benefit, especially if backed up by trained groups.
"Untrained dumbass with gun" is not a valid military strategy. (In fact, it more closely matches the contemporary british tactics: stand in the open and shoot vaguely in the direction of your target)
Especially considering that modern military training consists of desensitization to combat and programming automatic reactions to otherwise problematic situations, along with weapon maintenance and physical training.
Of course, I'm also not sure what the fuck situation you think would lead to civilians taking up their cheap hunting rifles and handguns and forming a resistance movement, as in that would, at best, end up getting them all killed, and if it was an invasion, their families and friends too.
It's not like in a country as massively decentralized as the US a civilian militia could effect meaningful damage. They could, at best, topple the local government (which wouldn't really make much sense, since, unless they were in an extreme minority, they would, in all likelihood, have elected people that agree with them), and then they'd be slaughtered by a SWAT team or, failing that, the national guard. And they'd serve as an example that would dissuade others from trying the same.
Even were the government toppled by the people (which isn't a possibility: before dissent reached the point of armed conflict, you'd get a disintegration of the union, leaving states that either end up dictatorships, or pander more closely to their populace, both of which nullify the possibility of armed revolt), it wouldn't result in some anarcho-libertarian wet-dream, you'd just get warlords and mafia organizations, and then probably foreign invasion or a nuclear holocaust.
...Or they decide the legal system would be much easier without the fifth amendment...
And instead it will be replaced by a system of agreeing to things you didn't commit at the threat of being tossed in jail for a much longer time if you don't agree... wait a second...
I can't tell if you're missing the fact that he was employing a slippery slope fallacy, or if you're alluding to plea bargains.
Now, there are valid arguments for allowing people to own guns, and carry concealed handguns, so long as that's also regulated so that criminals and the mentally unstable can't legally purchase them. "We's gonna overtrow dem tyrants!" is not one of them, and honestly is a pretty good indicator that the individual in question isn't mentally sound enough to own firearms (or sharp objects) in the first place.
