Freedom is not free

The Second Amendment has nothing to do with hunting.  Its purpose is to enshrine and protect the right and ability of the Americans to defend themselves from tyrannical government, but that is not all - it describes more than just a right. In DaddyBear's blunt, yet eloquent terms:

My gun rights aren’t for hunting deer or shooting skeet. They’re for hunting dictators and shooting tyrants.

DaddyBear is exactly right - the Second Amendment clearly describes the role that the average citizen plays in maintaining his own freedom and that of his neighbors.  It describes this role straightforwardly and without equivocation:

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.

Let's break it down and define it piece by piece:

A well regulated militia - The people, armed, disciplined, and trained
being necessary - are needed
to the security of a free state; - to prevent tyranny in their own government;
the right of the people to keep - the people have the right to own
and bear arms - and carry weapons
shall not be infringed. - and this right is inviolate.

And putting it back together, the amendment reads:

The people, armed, disciplined, and trained are needed to prevent tyranny in their own government; the people have the right to own and carry weapons and this right is inviolate.

The Second Amendment clearly describes not only a right, but a sacred duty of the people - to stand tall and defend liberty from the enemy within.  While armies are raised in response to threats to the nation, the people must always be vigilant and active in the defense of their liberty from attacks by their own government.  That is the true meaning of the Second Amendment, that is its purpose.

The tank, the B-52, the fighter-bomber, the state-controlled police and military are the weapons of dictatorship. The rifle is the weapon of democracy. Not for nothing was the revolver called an "equalizer." Egalite implies liberte. And always will. Let us hope our weapons are never needed — but do not forget what the common people of this nation knew when they demanded the Bill of Rights: An armed citizenry is the first defense, the best defense, and the final defense against tyranny.
Abbey's Road (1979)

You are the last line of defense.  You must stand, when all others fall or become corrupted.  Freedom is not free.  When the oligarchs are calling for the confiscation of your neighbor's weapons, remember your duty - to defend your liberty.  Liberty lives or dies on our action or indifference.  Freedom is not free.  If you think your government would never become an instrument of tyranny, think again.  Remember that they did just that during Katrina, they herded people into the Superdome and would not let them leave.  They confiscated firearms, leaving people defenseless in the face of looters and thugs.  They shot unarmed men in the back.  Freedom is not free.

No, my friend, freedom is not free.
