"What part of "Well-regulated militia" do you not get?"

I understand that the Founding Fathers had just recently concluded a very bloody and protracted war of rebellion against their (then) lawful government, and that a citizen militia was crucial to their success... if it hadn't been for the citizen militia, we'd probably still be singing "God Save The Queen."  Those incredible minds also understood intuitively that any government they might devise, even with their intricate system of checks and balances, could eventually devolve into a similar "long train of abuses and usurpations."  Heck, some on the left believe we're at that point, now.  They were determined that future generations would always have the means of rising up against that eventuality by forming a "well-regulated militia."

I also understand that the Heller and McDonald SCOTUS decisions rendered that clause moot as it pertains to individual firearms ownership.
