Do you really see "that many Christians" killing in the name of Jesus? Compared to Islam it's not even close.
edit: Clearly by what you highlighted in my OP I'm aware of the occasional abortion bomber and recognize that violence exist in all sects of all religion. My point is the amount of violence committed by people in the name of their religions compared to Islam is incredibly low. Your meme doesn't add anything to the conversation.
He will just ignore the fact that the IRA was group that assimilated to fight British rule. The last time I checked Great Brittan is Christian in most accounts.
He will also ignore the fact that the crusades happened between 1095 to 1291, well before the modern era AND were in response to Muslim nations conquering Christian cities.
He will also ignore the fact that Abortion clinic bombings were perpetrated by lone wolves no working with any organized religious group.
All he has is the KKK and I bet if we were to compare the number of Klan members and sympathizers to the number of radicalized Muslims and their sympathizers, calling the difference lop sided would be the understatement of a lifetime.
