It is wholly and completely true. The Constitution was created by the Government born of the Declaration. If the principle of a God given right to leave is wrong, than the government that created the Constitution was illegitimate.
There are people who believe that our Constitution is divinely inspired. So, what happens if there is a conflict?
done in Convention by the Unanimous Consent of the States present the Seventeenth Day of September in the Year of our Lord one thousand seven hundred and Eighty seven and of the Independance of the United States of America the Twelfth In witness whereof We have hereunto subscribed our Names,
A reference to the power from which their authority is derived. That power trumps the written words of man.
How can anyone disagree with that? The obvious problem is that people often disagree about what God wants.
The Founders of this nation all agreed that he wanted people to have a right to leave a government that no longer serves their interests. They founded a nation on the premise that this belief is true. That nation then created the "Articles of Confederation", and then subsequently the "Constitution of the United States."
Never forget from whence flows the authority of law in this nation. The order of legitimate authority is God, The Declaration, and then the Constitution.
The Declaration is the grandaddy of all law in this country.
I don't know how many times I've tried to agree with you that this isn't a prison. If you want to "leave," you can leave.
Governments are created by people. Plants don't create governments. Animals don't create governments. There is no known earthly force other than people that creates governments. It follows that people have the power to create governments. They have the power not to create governments. They have the power to create new governments. They have the power to stop having governments. THERE IS NOTHING PROFOUND ABOUT ANY OF THESE FACTS. It is the details that trip you up.
There is a distinction between you and the people as a whole. The fact that you may want a particular type of government does not mean that the people as a whole want the same type of government that you do. When different people want differing forms of government, it is pointless to say that the people as a whole want any particular form of government because we have just stipulated that they disagree about the particular form of government that is desired.
Maybe you just can't accept that other people may have different interests than you and if you can't, then this presents an impossible situation for you to understand. But, the interesting questions concern what should be done when different people have different notions about what kinds of government they want because that is the way the world has always been. There has never been a unanimous people when it comes to these questions.
Politics concerns how we resolve these differences. Should they be resolved by war? By vote? You just skip all of this by saying that people are entitled to the government that they want and you just ignore the reality that they want different things. You pretend that there is a "people" that is unanimous in what it wants and your question is always, "So, why can't the people have what they want???"
I want you to just try to hypothesize the existence of a group of people who are not unanimous in what they want when it comes to government. What should be the result? This is the question that you need to start addressing because that is the reality of our world. You can ignore that question if you wish, but the rest of the adult world is going to continue to deal with that question, with you or without you.
Beyond all that, if you never get around to considering political questions about what to do in a world that is not unanimous in thought, there is something in the Declaration that is important for you. There is the reference to the "pursuit of happiness." The document does not grant you a right to happiness, but it claims for you a right to pursue happiness. I encourage you to do that. If that really requires that you leave, then you should probably leave. But, look around first. I don't think you're going to find a better place to go.
