The so-called New Atheists, like Richard Dawkins, maintain that religion in all its forms is bad. They cite the acts of terrorism being perpetrated today by extremist Muslims, and then assert that all religions lead inevitably to violence and killing. With specific regard to Christianity, they point to the Crusades, the Spanish Inquisition, and witch trials as proof of their assertions.
There is much to be brought to bear against these claims, but I won't spend the time here. The reason for this post is to once again bring your attention to a thoughtful post by my friend Bob Perry. Go here for a clear comparison of the deaths for which professing Christians can be blamed and those for which an atheist worldview (like that of Dawkins) is responsible.
