This is very common in the university environment where I work. Many of the people here have ties to Europe. They will invariably reply to me when I ask them where our rights come from, that “The Constitution gives us the rights.”
The idea that the rights were by-and-large given to us by the Creator, as put forth in the Declaration, is totally foreign to them, as is the idea that the Bill of Rights much more tells us the rights that the government cannot take away.
I point out to them that their approach was tried in Europe with the European Constitution. When it got to be up around 700+ pages, with all of the rights (to health care, education, so many hours in a work week, enough vacation days each year etc etc etc) it COLLAPSED OF ITS OWN WEIGHT. They have not had any luck reviving it since then.
What’s ironic is that it was European thought, as expressed in the books and writings that influenced our founders, that lead to this very system. Hell, some still argue we have a democracy, not knowing it’s a republic and why that matters.
