You get it.
I do not have time to write a dissertation, but will quickly jot down some quick points to help you see this clearly.
The Declaration of Independence sets out the rights of man. It is a declaration to inform the King of England of the basic rights (irrespective of government) of Man-kind (to include women), to unify the colonies against England, to convince Americans loyal to England that England had violated their rights, and to garner support from other nations. Basic theme is the Rights of the Individual. Governments can be formed to insure these rights.
"LOL, try being happy with ill health."
The document does NOT say man (or women) have a right to happiness... they have a right to pursue happiness. BIG difference.
The Declaration did not infer it necessary to believe in a creator. As a matter of fact the first draft said man was "created" with these rights. It is not exactly known at what point “Creator” was inserted. Jefferson's intent was "created" and not by a Creator. However, given the intended multiple audience, it was somehow changed.
The Declaration of Independence is not the Constitution of the United States. And the authors of the Constitution could not foresee all required statutes and rights that would stand the test of time. That is why there are 3 branches of government to serve as a system of checks and balances, and specific rights are spelled out in the Bill of Rights. Additionally there was, and is, the need to allow the Rights of the individual States along with the Rights of the Nation. This was a delicate balancing act to get all the colonies to join the new nation, and gain independence from England.
The Constitution did not exempt the rights of Blacks and women. Blacks were granted the right to vote in most of the northern states when those states created their own State Constitutions in the period of 1776-1784!! Do your research on the Black Vote during the 1700's. I think you will be stunned. During this period of time, Baltimore had more Black voters than white.
Women also had the right to vote in several states starting in 1776, and some of those were rescinded later… by States. The issue here was State Rights versus Federal Rights. Because the Constitution is a living, breathing document, these rights were universally granted by the 19th amendment in 1920.
Mankind is fallible, and this living Constitution was designed to overcome that. And to protect these rights, the people (government) can take actions against those who violate the rights of individuals; e.g. your incarceration question.
It has provisions for revisions, as the authors intended. It can never become a dinosaur, unless the U.S. self-destructs under the burden of socialism. So it is NOT a DINOSAUR, but one of the greatest documents ever written.
And although I am upset with what has happened in the US over the past 80 plus years, I still feel it is the greatest country on earth to live in, and it still has the ability to protect the individual rights of mankind. I would never, ever consider moving to another country.
The problem I see today is that we have passed laws that restrict the individual rights of mankind, by embracing Marxism, communism, socialism, altruism, and all sorts of immoral systems that restrict the individual rights of mankind.
Today in the US, the Tea Party is quickly providing an awaking of individual rights. I am not a Tea Party member or advocate. But they are exercising the right to change the government.
