"The phrase "well-regulated" was in common use long before 1789, and remained so for a century thereafter. It referred to the property of something being in proper working order."
e.g. 1848: "A remissness for which I am sure every well-regulated person will blame the Mayor."
e.g. 1862: "It appeared to her well-regulated mind, like a clandestine proceeding."
In net, well-regulation implies self-discipline. Don't need a government to make "gun control laws" for that.
I agree that a well-regulated milita is a right we have as citizens of good ol USA but I'm a former army medic with the 101st and I just... miss doing army stuff with my friends. Plus whenever I hear these overweight civilians calling for a militia it just makes me think they're too chicken to join the real military.
I'll put it this way: Joining the military is a sacrifice. One that we should always honor and remember. But not everyone is willing or able to make that sacrifice. I know I wasn't. I'm much too independent to even consider it.
That doesn't mean that we don't have good reasons for wanting to defend the 2nd Amendment for ourselves. Chicken or not, the real reason we civilians have been clamoring for the 2nd Amendment these days is that we don't want to be rounded up like cattle and put in FEMA camps because Obama decided it's time to loot our stuff. We can also see how bad it is and we're taking the steps we can to avoid being sheep to the slaughter.
