More than 140 college campuses in 36 states have held anti-war rallies denouncing the country's military actions in Afghanistan, the report says.

The document — "Defending Civilization: How Our Universities Are Failing America and What Can Be Done About It" — concludes that many professors and administrators are quick to clamp down on acts of patriotism, such as flying the American flag, and look down on students who question professors' "politically correct" ideas in class. The report was completed last month.
