The principle that all men have rights.
That was meant at the time of the writing of the Constitution to mean “All land owning men of good standing”. That alone was rather radical, and was preached against in Europe.
Saying you have “rights” is a moral statement. It says that even though one party has the power, they are not allowed to use that power against someone else. It is a moral statement just like “do not murder” is.
Read philosophy and history sir. The Constitution and the Bill of Rights was very radical for it’s time, and was attacked for intruding to far into the moral sphere of the landed gentry.
"Saying you have “rights” is a moral statement."
I asked what the moral principle was that made it a moral statement. Simply repeating that it is a moral statement isn't proof of your opinion. I could, for example say that it is a philosophical statement and not a moral statement.
Morality is about what is right and wrong. People can have very different codes of morality. In the age of reason, we the people created and adopted a Constitution that codified a Government based on said reason, and the observation of Nature as a reflection Natures God. However, it was recognized that Government could not take the place of God nor be a moral arbiter in all cases. We the people limited the powers of Government to only those powers enumerated because we knew a Government of unlimited powers is destructive to liberty.
In other words, just because you think something is immoral doesn't make it something the government has the legitimate power to regulate. Otherwise our Government becomes one of unlimited power that destroys liberty based on some tyrants demagoguery of "morality".
