I blame the person. If a person uses religion to spill blood that's the person's fault.
You give me a book with multiple meanings and I can turn the most peaceful message into a war cry and a page about sacrificing into a humbling message about the evils of being materialistic.
I'm not a Christian but all I have to do is get enough people to agree with me to give me sway, say it with enough convection, completely throw out my moral system and I could make some profit, or maybe start my own cult. Look at Petter Popoff (spelling may be wrong) excellent example.
People kill for many reasons, but it's easy to hate on religion as a reason.
The same way it's easy to hate on "Assault Weapons" then in reality they don't really kill that much people when you look at it in perspective.
Um... The inquisition. The crusades. The Dark ages. AIDS epidemic. Teen pregnancy.
But yeah. Christianity is a benign and non violent religion.
