The Declaration of Independence is a political manifesto, not a legal document. Anyone who has ever taken a civics course in the past 100 years or more knows that.
Then you are also ignorant about the D of I. The Decl. of Independence is codified as organic law in the U.S. Code. Judge Roy Moore has been using that as an argument in his 10 commandments case, and it's a simple irrefutable fact. Before you make assertions, why don't you check out the facts first? You are wrong. Why don't you look it up and see for yourself?
Evidently you are the one who doesn't know his civics! Next time, maybe you better check to MAKE SURE what you are saying is true before you say it. I am 100% CERTAIN that what I say is true. I can't help it if you don't know about it. Go look it up.
