Please don't take the following as a flame, because it's true:
Majority of people in the USA feels threatened that these very principles you mentioned are under attack from Muslim religious fanatics. Their internal media also has a hand in it, but so does the large number of 'nuts' present in your country.
Only the Faux News crowd believe the nonsense about the 'freedumbs' being under attack from the 'terrists'
Let's examine the Bill of Rights and see who exactly is attacking these freedoms...
