In the second paragraph of the Declaration of Independence it begin with "WE hold these truths to be self evident". Who were the "We" ? All of those in attendance were white men and they said "All men are created equal" I think they meant all white men are created equal. They did not include slaves,indigenous people or women as as being the beneficiary of the inalienable rights. Since no one in any of these three classes could vote or own property they obviously were not initially endowed with the same rights as the white men.
Eleven years later when the Constitution was being drafted slaves were acknowledged as 3/5 of a person while women and Native Americans were still unrecognized.
