YOU may interpret it any way you wish. The founding fathers most certainly did not:
"Arms in the hands of citizens may be used at individual discretion in private self defense." - John Adams
"I ask sir, what is the militia? It is the whole people except for a few politicians." - George Mason
"The Constitution shall never be construed to prevent the people of the United States who are peaceable citizens from keeping their own arms." - Samuel Adams
"The Constitution of most of our states (and of the United States) assert that all power is inherent in the people; that they may exercise it by themselves; that it is their right and duty to be at all times armed." - Thomas Jefferson
"The laws that forbid the carrying of arms are laws of such a nature. They disarm only those who are neither inclined nor determined to commit crimes.... Such laws make things worse for the assaulted and better for the assailants; they serve rather to encourage than to prevent homicides, for an unarmed man may be attacked with greater confidence than an armed man." - Thomas Jefferson
