I see you have the same problem the NRA has: You think the Second Amendment begins with an ellipsis. Instead, it begins with words:
A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.
What part of "well regulated Militia" and "security of a free State" has to do with your right to own a gun for your individual protection?
I know very well why we have a Bill of Rights. It was to ensure that certain actions of the government were explicitly excluded. And just to make sure, the Ninth Amendment explicitly states that the Constitution is not a laundry list. You have rights that aren't mentioned in the Constitution and yet are still protected by it:
The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people.
Has it occurred to anyone that your right to own a gun for personal protection might be a Ninth Amendment right, not a Second Amendment right? Of course not. Everybody's knee-jerking. You saw someone saying that the Second Amendment doesn't say what you think it says and you immediately assumed that I was some anti-gun freak, right?
The Second Amendment is clear: You have a right to own a gun because the State might need you to help defend it.
What does that have to do with your right to own a gun for personal protection?
