Throughout the history of the U.S., the states, Congress, presidents and judges have rewritten nearly all of it, despite the idea that it was intended to be the final word unless altered by amendment.
Since the meaning of the Constitution and everything it contains is subject to the whims and fancies of the aforementioned entities, it has become little more than a doormat smudged with the dirty footprints of those who have twisted it over time.
You speak truth. Glad you enjoyed revisiting the "intent" of the Constitution in regard to the Second Ammendment.
