According to a new nationwide online survey of 600 Muslims living in the United States, significant minorities embrace supremacist notions that could pose a threat to America’s security and its constitutional form of government. 

"... nearly a quarter of the Muslims polled believed that, “It is legitimate to use violence to punish those who give offense to Islam by, for example, portraying the prophet Mohammed.”

By contrast, the broader survey found that a 63% majority of those sampled said that “the freedom to engage in expression that offends Muslims or anybody else is guaranteed by the U.S. Constitution and cannot be restricted.”

"... third category of Muslims that lurks between “moderates” and “radicals”: “sleepers,” Muslims who appear “moderate” but who are merely  waiting for circumstances to turn to Islam’s advantage before they join the jihad; Muslims who are waiting for the rewards of jihad to become greater than the risks.

There is no lack of examples of these types of Muslims." 

We are constantly told that only a tiny minority of Muslims hold extremist views and that Muslims make wonderful citizens. But a recent survey refutes all of this optimistic propaganda.

The survey tell us that significant numbers of Muslims in America do not want to be ruled by our Constitution but want Sharia law. Nearly a third of the Muslims said that violence to enforce Sharia blasphemy laws are acceptable. Nearly 10% of American Muslims say that Islamic State is real Islam.

Why do we want to admit more Muslims who oppose our laws and customs? How can Muslims be true citizens of America?

Center for Security Policy President, Frank J. Gaffney, Jr., observed:

Carefully consider why our government is admitting more and more Muslims into the United States of America who oppose our laws and customs?  Ask yourself, "How can Muslims be true citizens of America?"  What could possibly go wrong?
