Trying to dodge and re-define "well-regulated" by claiming it actually meant something else in the past is just that -- a dodge, a falsehood. The word "regulate" in English has meant "to govern by restriction" since its first uses in the 1620s. Source:

You fail at English.
To govern by restriction has fuck all to do with making laws. A dam governs the flow of water by restriction. Weights and springs govern the keeping of time by restriction. A governor is not just a guy in office.
A well regulated militia being necessary to the security of a free state, the right of the people to keep and bear arms shall not be infringed.
It's simple logic, militias are people keeping and bearing arms. People have even tried to argue this as being reason to restrict people from having guns because "the national guard" and joe schmoe are two different things. If militias shall not be infringed upon, well regulated cannot mean what you've convinced yourself it does.
A sentence gives a reasoned restriction on government, and asshats around the world gravitate to the one meaning a word can possibly have that comes in direct conflict with the rest of the sentence. Proof people are morons.
You are also hilariously wrong on what you think crime statistics show. You have over an 80% chance of being the victim of a violent crime before you die. Congratulations on being in the 4 out of 5, might I suggest not hitting on rednecks? I find it highly unlikely that you were shot at by a law abiding citizen, with exception to being shot at of course. Barring the redneck joke(you didn't, did you?), the odds are far better that you were shot at by some gang banger asshole that bought his gun from the same guy he gets his coke from.
No one actually keeps statistics on defensive gun use, but the surveys suggest the number is a million plus every year. There aren't even 20,000 homicides per year, and that's homicide, not murder with a firearm. Even if you look for the lowest estimates, defensive gun use beats homicide rates 4-1. Accidental shootings are a rounding error, we should outlaw bath tubs if we're going to start making decisions based on freak accidents and people not properly raising their children.
Those low estimates are assuming that everyone who draws on some punk that runs away bothers to report a crime to the police knowing they wont even bother to show up. Unless you actually shoot someone, they don't give a fuck. Most people aren't like me, they're squeamish about removing scum from the gene pool. Shooting is their last resort, instead of the primary response to a threat. As such it's extremely rare because few criminals are stupid enough to continue an assault when it becomes a choice between murder and death.
Move to the UK, they've all but eliminated hand gun ownership. You can enjoy getting knifed or clubbed instead of shot. Twice as often.
