Regrettably, you are correct. There are no innalienable rights. Just ask the Cambodians under Pol Pot what rights they had, or the Cossacks under Stalin. We have what rights we give ourselves. We are the masters of our own fate.
Being Created gives Moral Authority to the Author of the Creation. He can set rules and give inalienable rights.
Even if that were true, which it isn't, its irrelevent. Those inalienable rights only exist when a government predisposed to limiting its own power grants them. If you're mixing cement in a Gulag, you have no right to life, no right to liberty, and certainly no right to the pursuit of happiness.
And when a body of men reason new rules that violate the Creator's standards we can fight, as they have no right to rule over us outside the Creators standard.
We can fight whenever we feel like it. The Joint Chiefs of Staff could lead a coup tomorrow, if they wanted to, regardless of any justification. Again, if there are any standards, they are completely irrelevent. You either agree to live by the rules, or you don't.
You always have those in-alienable rights, regardless of whether you are oppressed or not. That is Morality. A standard that no man can change or remove. A level of life that cannot be reasoned away by intellectuals that have no concept of what they do not know. A force that gives the moral being to those that fight for freedom. A righteousness that prevails in all times and in all darkness.
Let me say that I am thankful that our men of war, our men of history were not the hopeless wanderers that you have become. I am thankful for the moral fiber that propels all righteous men forward into duty and honor. Honor to that morality, to those in-alienable rights handed down by the Creator. The Creator that make your life valuable enough to sacrifice theirs to protect.
