As you alluded to, "well-regulated" at the time meant something that functioned well; however, something you seem to have forgotten is how militias function.
In a professional standing military, you can afford to take in any Tom, Dick, and Harry that can't shoot, and you can afford to throw ammo at them until they don't suck. In a militia, you don't have that luxury. You get what you get, and there isn't much funding for training, much less actual equipment, as most militia are banded together for an emergency post-haste with equipment on-hand.
Position 1) The right is necessary in light of training requirements.
If the people can't shoot, how much use are they in a militia? You can only have so many cooks and back to carry a load. Clearly then, without a citizenry capable of practicing skill at arms on their own time and dime, the likelyhood of raising a functioning militia on short notice is dismally slim. Lastly, if you were to pull together a militia of people who grew up scared that their uncle's
Position 2) The right is necessary in light of logistical requirements.
In short, the logistics of maintaining an effective short-notice militia are a nightmare. As stated previously, militias were usually called up in rediculously quick order with whatever they had on hand. In the vast majority of areas, there were no armories were everything was stored, short of a place for their cannon, if they had one, which was usually privately owned as well. (gasp) Instead, everyone brought what they had at home. Hard to muster an effective militia if you have no weapons.
Also, I'd take issue with your idea of what a militia is or is not. Technically, if one were to attribute gun-ownership to everyone in the military, by definition then, it would be a vast number of unrelated gun-owners, though I do believe you meant related more like organizationally related as opposed to genetically related.
In that case, your case still fails:
US Code, Title 10, Subtitle A, Part 1 > Chapter 13 Â 311 Militia: composition and classes
(a) The militia of the United States consists of all able-bodied males at least 17 years of age and, except as provided in section 313 of title 32, under 45 years of age who are, or who have made a declaration of intention to become, citizens of the United States and of female citizens of the United States who are members of the National Guard.
(b) The classes of the militia areâ"
(1) the organized militia, which consists of the National Guard and the Naval Militia; and
(2) the unorganized militia, which consists of the members of the militia who are not members of the National Guard or the Naval Militia.
According to current US law, the unorganized militia consists of everyone who is a citizen from 18 to 45, gun-owner or not. Somehow I don't think you were aware of this, much less the fact that you are technically obligated as a militia member the moment you reach the age of majority. Kinda puts a different spin on the draft, eh?
Unfortunately, a lot of the anti-gun variety like to throw out the National Guard as being the militia, seeing as the Federal Government aborbed state militias into the National Guard in the 1800s; however, if one paid close attention to the founding documents, the militia at the time were all run by the states. The National Guard is run like the bastard stepchildren of the US Army, a Federal organization. Seeing as the militia at the time were state-based, how could the National Guard possibly be what the founders envisioned? Keep in mind that the National Guard did not exist until 1903, over a hundred years after the Constitution was written.
I'm sorry if your lack of knowledge of both the functioning of a military unit, US law, or your closely held political beliefs got in the way of the truth; try again, this time without the blinders on.
