Muslims discovered America?

A Native American tribe has forced distributors of an Arab studies guide for American teachers to remove an inaccurate and absurd passage that Muslim explorers preceded Columbus to North America, and eventually became Algonquin chiefs named Abdul—Rahim and Abdallah Ibn Malik!
 
The Middle East Policy Council, a Washington advocacy group that promotes this curriculum to school districts in 155 U.S. cities have apparently been somewhat unresponsive and dismissive of complaints. Ridiculous as this example is, it is illustrative of a far more disturbing development: the placement of propaganda in our schools by Muslim extremist groups. As the Thomas B. Fordham Foundation pointed out in a report issued this week titled, "The Stealth Curriculum:Manipulating America's History Teachers" these efforts are intended "to use America's public school classrooms to shape the minds of tomorrow's citizens by manipulating what today's teachers introducing into the lessons of today's children"
