It is not about "human freedom." It is about asserting a right to be independent from a Union.
People subsequently claimed it was about "human freedom", and they base this entirely on those five words from Jefferson, but the document was not in fact about this.
People have made the document into a claim about "human freedom", but this is not at all the reason for it's existence, and is an example of "creative interpretation" to twist out a meaning that wasn't intended by the signatories.
The basis for the independence is individual human rights. “All men are created equal” Why are you spinning so hard to deny what is right there in the document? Cleanse yourself and stop the nonsense.
