Well there's one qualifier right there. The American Mythos of "all men are created equal" has failed to line up with the American reality for quite a long damn time and for reasons that don't require much more effort to "qualify" than is needed to lift up an arm and point at a history book. It's been qualified, documented and analyzed thoroughly enough that the qualifiers should be abundant and "self-evident"-to continue the trope of quoting directly from the user's manual.
The long arc of history of the US bends towards that phrase becoming more true, but there's still a long way to go for everyone to be demonstrably accepting of it.
Although it would be the first data point in an outline of what would be my infinitely-less abridged critique of the “American Mythos”, under which many, MANY others would invariably fall-it is still at the end of the day only one.
The others would probably include a few one liners shamelessly stolen, but dutifully attributed to Hunter Thompson, James Baldwin and Cormac McCarthy. Could probably fit Howard Cosell in there too now that I think about it.
Decontextualized, the fundamental rights Americans celebrate are at odds with each other (right to life and right to liberty are the obvious examples, and some good criteria for discerning how to maintain those in coexistence has been established, but others, like "Freedom from fear" or "Freedom from want" and "Right to liberty," are much, much murkier. And this is all, of course, in the context of an ever-changing world that brings new technologies and experiences that must be interpreted against those rights).
Uh... I'm not sure what it is that you are trying to say, or if you are sure of what you are trying to say, or if you have a very appropriate username.
Moreover the freedoms [0] that you mentioned are aspirational. Also, not the constitutional freedoms of speech and religion, which are enshrined therein.
