"It says' well-regulated.' You gun nuts keep forgetting that."

The President shall be Commander in Chief of the Army and Navy of the United States, and of the Militia of the several States, when called into the actual Service of the United States
The Civilian Marksmanship Program (CMP) is a national organization dedicated to training and educating U. S. citizens in responsible uses of firearms and airguns through gun safety training, marksmanship training and competitions. The CMP is a federally chartered 501(c)(3) corporation
The Office of the Director of Civilian Marksmanship (DCM) was created by the U.S. Congress as part of the 1903 War Department Appropriations Act. The original purpose was to provide civilians an opportunity to learn and practice marksmanship skills so they would be skilled marksmen if later called on to serve in the U.S. military. Formation was precipitated by adoption of the M1903 Springfield rifle as the national service arm. Civilians experienced with popular contemporary lever-action rifles were unable to sustain an equivalent rate of fire from the unfamiliar bolt action M1903 rifle.

But as someone reminds me, that is once again the second part of the problem. Here's the first part:

"A well educated electorate being necessary to the security of a free state, the right of the people to keep and read books shall not be infringed."
Who has the right to keep and read books? The people, or the well educated electorate?
"A nutritious breakfast being necessary to the development of a healthy child, the right of the people to keep and eat food shall not be infringed."
Who has the right to keep and eat food? The people or the nutritious breakfast?
No, you anti-gun nuts have simply never understood that. Defined, subject to order, provided with a means of training. That constitutes "Well-regulated."
That YOU are 100% derelict in your duty to the nation is no surprise--you're liberals, after all.
