It is not for people not long suffering assaults on liberty to judge when the suffering had had enough. You will note Jefferson said it was not only their right but their duty.Hey buddy, your belief is incorrect. What the Declaration of Independence said was:
"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 inalienable 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."
That is the basis of your assertion ?
Well, you conveniently leave out the rest of Jefferson's Quote. The part that gives it context and meaning the part that obligated the United States to crush the Confederacy.
The rest of Jefferson's quote is as follows:
"Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shown, 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 took pains to argue that the right of revolution was a limited one, in the sense that one could not do this for weak or frivolous reasons (or “light and transient causes”).
Your argument falls flat unless you realize that the union had the same right under your premise.
Show me where your magical right of secession is enumerated in the Constitution and the Bill of Rights.
Remember the constitution was enacted via the votes of the states. That that a free people can vote to accept they can vote to unaccept.
Show me that part where it’s ideas accepted the people were bound to it sans recourse. The framers of our country did not aim to replace a human tyrant with a paper one.
