Thomas Jefferson made it clear that all men have a right to defend their property and a right to defend against tyranny and a duty to throw it off when it becomes tyrannical and unlawful. This is the true purpose and intended use of the Second Amendment:
“IN CONGRESS, July 4, 1776.
The unanimous Declaration of the thirteen united States
When in the Course of human events, it becomes necessary for one people to dissolve the political bands which have connected them with another, and to assume among the powers of the earth, the separate and equal station to which the Laws of Nature and of Nature's God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation.
We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.--That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, --That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness. Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security.--Such has been the patient sufferance of these Colonies; and such is now the necessity which constrains them to alter their former Systems of Government. The history of the present King of Great Britain is a history of repeated injuries and usurpations, all having in direct object the establishment of an absolute Tyranny over these States. To prove this, let Facts be submitted to a candid world.”
Jefferson and every colonist knew that they could not have overthrown their British colonial system of tyranny with garden tools. The insistence of some like Piers Morgan, CNN, TIME WARNER, Obama; Nickolus Kristof; Connecticut Senator, Richard Blumenthal; Mark Glaze; NY Governor, Andrew Cuomo; VP, Joe Biden; Philadelphia Mayor Nutter; Philadelphia Police Chief, Charles Ramsey; and Alan Dershowitz, that individuals do not need anything but the smallest of firearms, simply deny the possibility of tyranny ever existing on the planet in the past, present or future. Yet they insist that to believe in the past, present or future existence of tyranny is a paranoid conspiracy theory that does not pass their mental illness test to buy a firearm.
Their continual rejection of the true purpose, use, and need for an organized militia says that they are in fact part of the force that is oppressing the people right now in violation of the US Constitution. It is obvious that they fear our defense weapons making it more difficult to push us around and to do with us what is against our will and to harm us with impunity.
