I see your point NW but I still contend that these values are not exclusively "American".
Constitution, from which I derive:
Religious tolerance
Free speech and press
Due Process of Law
The general welfare
Right to participate in government
Take:
Religious tolerance: Religious people of all kinds have managed to live side by side for thousands of years. Again it is those who control that are intolerant, the people could for the most part live in complete tolerance of varying religions. While our constitution has spelled it out for us and we are given that right, it is still not owned by Americans.
Free Speech and Press; America is no longer the leader in this arena, I think we are something like 20th in the world. Is it a value we embrace? yes and it is an important one. Americans while putting it in writing ( a good thing) have also allowed this "value" to be chipped away at. Given that Americans have allowed their country to no longer lead the world with this value, could it still be considered an "American Value"?
Due Process of Law: Again a very important value that we all believe in. Again another area where Americans have allowed their governing bodies to chip away at. Even though it is a deeply held value can we claim it as our own if we no longer lead the world in this area? If we allow our government to live above the law, can we still claim this value to be ours?
General Welfare: To be fair can you really name a country where you feel the massess didn't have this value? Not to mention that while we proclaim this be a "value" at the same time we live in a "me" society which contridicts this value.
Right to participate in Government; Good Value, one that what fewer than 40% of Americans actually take to heart. We have seen what people in other countries will endure to vote, yet here we sit with supposdly the most open government and what do we do with it?
I believe we as individuals hold "values" and how we embrace them and stand by them says a lot more about who we are then to tout having "American Values". I believe very strongly in everything you listed as I know most everyone does, I'm just saying that I put myself in the category as a person with those values being willing to stand with many in the rest of the world who can also hold them deeply in their hearts.
