"When, in the course of human events, it becomes necessary to [to kick the King's butt]...a decent respect to the opinions of mankind requires that [the rebel traitors] should declare [why they're kicking it]."
They called the public whine or statement "The Declaration of Independence". Apparently, instead of just picking up guns and shooting British soldiers—which after all most of the rich gentlemen were not going to be doing (dying for one's country is for the poor, dumb classes to do)—these literate freeloaders wanted the world to understand why it was necessary for them now to stop being British, and to start being—oh—whatever they might choose to be. Especially, whatever THEY might choose to be. Not whatever women, or indians, or especially black slaves might choose to be.
Whereas rich, white male American rebels felt they were entitled to the assumption of nobility and possession of unalienable rights (they) ascribed to that status, everybody else either had to earn it (i.e., get away with stealing it from some no-account victims like poor people and indians), or they were at best understood to possess some lesser degree of full rights, assessed according to wealth and power.
In the end, no matter what Thomas Jefferson, slave-owner, hypocritically rendered about "all men are created equal", the fact is that all people were not going to be treated equally, and for that matter, the majority of Americans were not even going to be counted as deserving of human rights, by the signers of the Declaration of Independence.
The question we should ask in 2012, as we should always ask on July 4, is whether the alleged ideal of universal liberty supposedly expressed in the DoI has yet to be realized, not only in the world, by in the USA itself. Much evidence points to what seems the obvious conclusion that the bold-sounding document is still describing a fictional, and maybe in truth an inhuman, utopia.
