As one who appreciates the essence of the issue I know that the 2nd Amendment is what can or cannot be altered by men. The RKBA is forever ours no matter what is said or written. I think Triple is right; to avoid the sophistries of 'Constitutional interpretation' being brought into the message, the 'RKBA' version cuts the debate off at the root. KBA's is a Right and treading on it is a lethal risk.
That's a message I can get behind. Though I'm sure that everyone posting here already knows it that message is not sent as a threat or even a warning issued in anger. It is simply a warning that says "I will defend myself and I will use whatever means I can. If you seek to deprive me of the means to defend myself that is a threat unto itself."
An unarmed man is whatever the powers that be choose to make of him. Subject, slave or corpse.
Institutions of authority have yet to make kings of any of them.
