Well, kelliekat, I'm glad you asked.
Your basic problem is that you are reading the Constitution like a real estate P&S agreement, where all meaning and right has to be derived from the terms within its four corners, and no reference made to the background or oral discussions preceding the finalization and signature of the writing. For statute and Constitutional law, however, the norm is to look at 'Legislative history' when opinions differ about what particular carved-in-stone words were meant to say, and the papers of the Founding Fathers make it pretty damned clear that they were indeed talking about an individual right, not a collective one, in the Second Amendment...and it is not mere coincidence that all the rest of the first eight articles of the Bill of Rights concern individual, not collective or governmental rights, with the provision on guns coming between the first and third of these.
Now go back to watching Oxygen and stop bothering the grown-ups.
