Ever since 9/11, the mood has changed quite a bit, and for the worst. The main cause for this change are the merchants of fear, who want to make us believe that Muslims are the new evil. By hammering on the assumption that all Muslims are terrorists who try to destroy the American society, they make people feel so very scared that some have accepted any kind of freedom-lessening measure, as long as it makes people feel less unsafe. That's not only the case in the U.S., the same goes for Europe.
