The US Constitution is the “contract” which authorizes the federal government to exist, which gives the government its sole legitimacy. That seems obvious when stated like that, but many people don’t think about it. The US federal government is there and always has been there and does whatever the President says it does.
That way lies tyranny.
I’d argue we’re already there. The federal government blatantly disregards the document, the contract, which authorizes it.
The US federal government has no legitimacy.
The US federal government now operates only by chicanery and naked force.
Given this, what is the moral obligation of the citizenry to support the US federal government?
As it was then, orders of magnitude worse now, which renders it damned nigh impossible to argue with a single word. I haven’t the least intention of making myself look foolish by attempting to, either. That way lies self-beclownment.
