Granted, we would argue that the acts described below during the Crusades were not the acts of "true" Christians perhaps. And, granted, there were horrible things done by them as well. But, these are events in history that every Muslim knows about and few in the west like to remember. And muslims tend to throw all Christians in the same category just as we often stereotype them. How long does it take for the memory of such things to disappear from a culture? =========== December 12, 1096: The small city of Ma'arra east of Antioch, falls to the crusades. The crusaders shock the Muslim world by eating human flesh from the adults and children massacred following their conquest. The Frankians would forever be referred to by Turkish historians as "cannibals". July 15, 1096: Jerusalem falls to the crusaders, who kill almost all of its inhabitants. An estimate of 70.000 to 100.000 civilians are murdered.
