Why the 2nd amendment is important:
We migrated to the United States to escape oppressive totalitarian government.
The concept behind the United States is that the centralized federal government has limited power over the people (as opposed to the dictatorships from which we came)
The Second Amendment states that in order to maintain a free state, the people must retain the right to keep and bear arms. The presence of armed citizens is what keeps the government “honest”. No government would be foolish enough to impose a dictatorship on people who have the ability to resist.
The Second Amendment does not grant us this right. This right already existed. The Second Amendment merely prevents the government from infringing on it.
