What most Americans fail to realize that the Declaration of Independance, while an inspiring piece of rhetoric, has absolutely no legal standing. We weren't even a country when it was written, and did not legally become one for quite some years afterwards.
Yep.
And, as I pointed out, the Constitution (including the Bill of Rights) draws its authority from "we the people" and not some notion of a deistic Creator.
But I think primarily what's going on here is just ambiguity. Inalienable natural rights and the rights in the Bill of Rights are two very different concepts. The former, as I've been arguing, is a principle that (it is claimed) is part of human nature that these are things every human
ought have. (Even if they're violated, we still hold that principle--it is inalienable in that way.) The latter are legal rights, which can often be thought of as limitations on the authority of government.
Claiming you have a right to 3 square meals, for example, is something different than claiming you have the right to be secure against unreasonable search and seizure by the government. The latter is something that we can always enforce, but the former really isn't. If no one gives you food, whom do you sue?
I think the union is introducing another idea yet, that would be better described as
entitlements. They think the government should have a duty to provide certain things as a safety net. In contrast to the idea of a
right to 3 square meals a day, if you have this sort of
entitlement to 3 square meals, and no one gives you food, then you sue the government whose duty it is.
