In the past 40 years, Saudi Arabia had invested 50 billion dollars in American Universities to indoctrinate Americans about Islam.  As a result, a generation of graduates of these universities have been exposed to lies about islam, and are now the teachers of Americas public school students.  Teachers and  Administrators are blind to these historical errors because they were taught to them as truth.  Now retired, a cultures public high school teacher who taught cultures/religions for 35 yrs. told me that the Islamic history of today’s textbooks is nothing like what was in his textbooks.
