 non-neutral and fringe source 

the book by rod stark is described as following:
""In God's Battalions, award-winning author Rodney Stark takes on the long-held view that the Crusades were the first round of European colonialism, conducted for land, loot, and converts by barbarian Christians who victimized the cultivated Muslims. Instead, Stark argues that the Crusades were the first military response to Muslim terrorist aggession."" 

this is utter nonsense, and represents a fringe view. the additions made by user daisy also violate wp:npov. in addition, there is a restriction-section covering the issue without violating npov or using non-neutral sources. "
