One of the most troubling elements in the propagation of Islamism and Islamic propaganda has been taking place in the last decade through control of what is included in social studies textbooks. No important textbook is published today without vetting by professors who are sympathizers of radical Islam, or beholden to Saudi dollars given to them in grant money.
In addition, The Saudi embassy sends “educational material” to schools across the country that social studies teachers are only too happy to use. It does not require research or preparation.
Now the Foreign Policy Research Institute has produced a ten-volume series for middle schools and high schools titled the "World of Islam" and published by Mason Crest Publishers, and CAIR is up to its old tricks crying anti Islamic bias.
Richard Pipes has a great article on the topic.
