Because Islam advocates the murder of infidels, their religious exemption status should be removed.
Actually, Islam should be treated as an alien and enemy political philosophy - not a religion.
You CAN be an American and practise Hinduism, Buddhism, Zoroastrianism, Wiccan, nothing or whatever, and still be a patritoic American. There is no political imperative in any religion.
ISLAM is different. Islam separates the world between the area controlled by Muslims and the area controlled by non-Muslims, it considers that a state of war exists between them, it enjoins its followers to impose Islam on the rest of the world by any means neccessary, and - most significantly, requires that a theocratic dictatorship, based on Islamic scripture, and known as Sharia, be imposed on Muslims and non-Muslims alike.
Islam is more of a threat to the west than Communism or Fascism ever was. Islam IS Fascism - wrapped up in a Theocratic Cape.
