One of the good things about this book is that Christopher Hitchens provides the kind of details of religious violence, not just for Christians but for Jews and Muslims and Buddhists and Hindus and on and on. So, he got good coverage.
It was also interesting that Hitchens is an Orwell scholar, so it connected with 1984 really well for me in places.
I may comment more later, but I'm typing with my thumbs now. I started listening to Kevin Phillips' American Theocracy.
