Supposed to ignore it ever happened. Remember: Islam is a Religion of Peace*
*No matter how many people are killed.
The lies that the American left tell us about the Crusades. Details, such as the fact that the majority or large minority of of the people in Syria were still Christian at the time of the First Crusade are ignored. Or the crimes perpetrated by the invadinf Seljuk Turks. The story is that a peaceful Islam was invaded by barbarians from the wild West.
