What about the Crusades?

Variety.com - Bound for 'Heaven'?:

"But the film has also been dogged in recent months by accusations that it short-shrifts real history. Jonathon Riley-Smith, one of Britain's leading authorities on the Crusades, labeled it 'Osama Bin Laden's version of history' and said, 'It will fuel the Islamic fundamentalists.' Islamic professor Khaled Abu Fadl of the U. of California accused the film of 'teaching people to hate Muslims.'"

I posted an article on the Crusades here. I wonder why Ridley Scott isn't being attacked for defaming Christians the way Mel Gibson was attacked for doing so to Jews with The Passion of the Christ.

I wonder?
