There were speaking about all of mankind, specifically all white male landholders. The language was specifically added by more liberal elements as I understand it (class was some years ago). Later this language was used as an argument to free slaves and include women. At no time have ai seen any evidence they meant only citizens.
However, I look at it differently than you do. I don't see those individuals at all. I see us as being subject to the rules. We, our people, soliders are subject to the laws and prinicples no matter who we're addressing because we are citizens. It informs us on how to behave. It's not only rights afforded, but rules of behavior.
And your poor nation esteem stuff is tiresome. By believing it our ideals in no way suggests I hate my nation. Quite the opposite. I believe in it's ideals and values. I merely want us to live up to them and not down to those ideals I see as less noble, those of the people we fight.
