The militia is the people. Not the state, national guard, or the federal government.
Actually a "militia" is an organized fighting ***** composed of citizens that can be called upon to defend the nation. So unless you're in an organized unit, and have a method to be called upon (some type of pipeline to the proper authorities allowing you to heed a call to arms) than you're not a militia. One man buying guns does not a militia make.
You're suggesting that there shouldn't be regulation when the amendment clearly states "A well REGULATED militia..." or did you miss that part? Probably why you omitted it, huh? Because it's inconvenient and you don't give a **** about the Constitution when it's not exactly working in your favor. Seems like the 2nd Amendment is perfectly fine with regulation... it even says that regulation is required for the "security of a free state".
