"...ABC ‘20/20' anchor Chris Cuomo is getting some flack-even from some of his fans-over a twitter comment about violence and religion. Cuomo told his nearly 1 million followers this morning: ‘To all my Christian brothers and sisters-especially Catholics-before you condemn Muslims for violence-remember the Crusades. Study them.'
A follower pointed out ‘by the time the Crusades began, Muslim armies had conquered almost two-thirds of Christian world. Neither just. ' Cuomo responded that he is ‘not sure how pointing out Muslim wrongs erases Christian wrongs.'
Shortly after the 9/11 attacks historian and author Bernard Lewis noted that the Crusades were in response to jihad and author Andrew Bostom wrote of the jihad-to-Crusade comparison that jihad is a notion contained within the Quran, while the crusades were ‘historical events subjected to ongoing and meaningful criticism by Christians themselves.'

Not the clearest of texts, from a source one can barely consider an objective one. But there is a lot of truth in it anyway.
