IN THE BOOK, The Two Faces of Islam, the author, Stephen Schwartz, goes into considerable detail about how Islamic supremacists influence politics and the media in the United States. The Wahhabis (a sect of Islam that takes the Koran's teachings literally) are a rich and powerful group in Saudi Arabia, and they have opened hundreds of mosques in the United States.
They've formed The Council On American-Islamic Relations, the American Muslim Council, The American Muslim Alliance, the Islamic Society of North America, and have infiltrated and are exerting control over the Islamic Circle of North America, The Islamic Association for Palestine, and the Muslim Students Association. These are powerful lobbying and public relations organizations, providing speakers at rallies, providing "expert commentary" for the media, distributing literature, holding rallies, and influencing American politics.
Through these organizations, the Wahhabis have had a powerful influence on the information that makes it to the airwaves in the United States because they have established themselves to the media as "the voice of Islam in America." They are extremely well-funded by an opulently rich group in Saudi Arabia. And they are well-organized, fully maximizing the freedom of speech and religion enjoyed in the United States.
They are infiltrating and influencing everywhere they can. They have the money and manpower and they are effective as long as we don't know what's going on.
