America's puritan based roots along with a continuing culture of anti-intellectualism will eventually be our undoing. This is slightly strange though given the premises on which our country was founded.
Like a lot of subjects, I think people find what they want when one talks about the founding of the United States of America. The slavery issue and treatment of native Americans that is the basis of the United States is pretty hard to get past as a founding principle, and I don't think it's a stretch to say they didn't consider women at all as being referenced in either document when they write "men", as many of the guys who wrote and signed that that were slave owners so they didn't even mean all human being males counted as men (except 3/5 of a slave for census purposes.)
