From what I gathered, there are a few facts on there but they are so oversensationalized and fed with so much propaganda and extreme bias that the entire point of that site is null.

As far as America is concerned, it sure as hell isn't perfect but it is a wonderful country to live in, even with all the morons and bad politics. People also seem to forget the many, many good things America has done and instead tend to dwell on the lesser amount of tragic things in its history. If you believe this for real, you are a very gullible and easily swayed person.
