seriously, I'm curious to know which government you want to be able to defend yourself against? The local police? The National Guard? The U.S. Army?
I have no idea what kinds of guns most local police officers carry around "every minute of every day" - one of these days if I have a chance I'm going to see if I can find out what weapons are available to most local police forces on an everyday basis. I think most just carry a pistol. I doubt the police in my community even have assault rifles, but I really don't know.
Most police forces have trained swat teams with assault weapons. The National Guard and various branches of our national military certainly have plenty of these weapons, plus others which are truly enough to shock and awe the average citizen.
So the plain fact that is most revealing about free human beings who are secure in their confidence that the government is "theirs", is that these responsible folks will universally use their personal weapons to defend "their" government.
It takes paranoid schizophrenics and/or other maladjusted humans obsessed with controlling the people in some specific way, or turning the government to their own purposes, to even worry about which way the people will use their personal arms.
So, dear blind Moe, please try to focus on the key fact. People will not use their weapons against "their" government, until something goes seriously wrong with "their" government, to the extreme that there is no more right to vote and no effective peaceable way to secure their essential rights. And that is the whole point here.
Perhaps to you should take a vacation or something to get away from the media, to the extent that you can objectively assess the world around you. Maybe notice some bees buzzing around some flowers, or admire some little bugs that have found some special niche in the universe where they can prosper, and display their beautiful red and black designs on your curtains or something, and relax enough about it you don't just have to be a control freak obsessed with killing the intruders transgressing into your personal control sphere.
People don't have to worry too much about bees if they can just leave them alone, or even box elder bugs. And if you can just own a little joy about seeing others things/people living in freedom, maybe life will seem a lot better somehow.
And governments don't have to worry about their peoples' arms as long as those governments are content to be those peoples' government.
There is just something missing in the hearts of folks who can't abide letting people be free. And they just can't stop themselves from worrying about what to do to make them do "just so", according to their own tastes in style.
Barack Obama and the whole liberal high command are just too worried about the people to be "OK".
And, by the way, the UN stated objective for world peace as planned way back when. . . . fifty years or more ago. . . . is complete disarmament of the civilian population, and some regulated sufficient number of government "military style" guns to put down any disturbances. . . . an ideal most dear to all statists with dreams of controlling central governments not answerable to the people, many of which do not have real representative government.
The whole idea behind the American government flowing from our revolution against British overlordship, is that people do indeed have the right to direct their government.
personal arms like "military style assault rifles" are today probably insufficient to exert power to curb a government that has turned on its people. The next line of defense is human decency, the unwillingness of even soldiers to carry out commands that are abhorrent to the people, even if given authoritatively by high officials. That line of defense has failed in many notable instances in the twentieth century, under the impact of serious propaganda campaigns.
If you don't see propaganda for what it is, you're just going to be going along with governance that is not really of the people, or for the people. . . . or by the people. There is a point of turning where it can become governance for special interests, or for some limited group of interests.
So here's my two bits. Socialism has never been "for" the people, it has always been a clever sort of substitute management which does in fact cut the people down to less than their natural dignity. But socialism is much loved by some cartelists/corporatists who love to have the inside track on influence, to their own benefit.
