If Communism, Oligarchy, or some other form of authoritarian, oppressive, persecutory and tyrannical government gains control of our nation and in turn its states, even if put in place by a gullible public, the right of the people to use those arms they own to wage war against such a government in order to get it back to being a "FREE" state under the original Constitution, becomes absolutely necessary.
A good example of this was the McMinn County War, also known as the Battle of Athens, Tennessee, in 1946, where veterans rose up armed themselves and fought against a corrupt government in that state, and won.
