No, no not every single Muslim is a terrorist.  It's just that, by far, if a terrorist act has occurred chances are great it was a Muslim.  On a side bar, the greater the number of victims the even greater likely, it was a Muslim terrorist.  But if you read the Qu'ran and understand Taqiyya, you would realize that ALL fundamental Muslims are called to arms.  Convert or kill all infidels is the creed. But Muslims that are American realize its their religious duty to be the best Americans they can be.  And are great Americans.  But for the rest of the world, the Sunnis and the Shiite have been  killing each other since the 10th century, when they split.  Each call the other infidel. You can't win!
