First off, I know more about the Bible than you. "What? A filthy atheist knows more about my doctrine which I base my life decisions on than me? Bullcocky." I was taken to church and scared into religion as a child. I was part of a church group called the Royal Rangers which was like a Nazi-camp, more religious version of the boy scouts. We would get medals and badges for passing tests based on Bible knowledge and outdoor survival skills. So I started studying the Bible at about age 9. Then because all I had to read as a child were my mom's romance novels and my Bible, I perused the divine in between looking for the "good parts" on a bearskin rug. Then at about age 17, I started reading variations of the Bible and books such as The Complete Idiot's Guide to the Bible, which summed up each part in a more original perspective. Then for the first few years of college, I majored in Philosophy of Religion and spent my time skipping class, but studying the materials out of fascination and curiosity. Then in basic training, the only book they would let you read was the Bible and since I'm a fast reader and didn't want to clean my rifle, I read it cover to cover at least 10 times. And on Sunday in basic, you could attend church, which got you away from drill sergeants and let you sit on comfy pews for a while, so I signed up for 2 different religions. And finally, my first deployment to Iraq had no internet access so I spent the bulk of my paychecks on B&N books by Harris, Dawkins, Hitchens, and Nietzsche. Then I branched out into the minority religions, such as Confucianism, Taoism, Celtic Polytheism, the Wiccans and their Earth Mother, ancient Egyptian religion, some crazy Gnostic branch where God was a female, etc. The result is the super-informed anti-christ you see today.
I find that atheists are more knowledgeable of the text they've rejected anyways, since most people are whatever religion they are based purely on demographics, upbringing, and lack of understanding of science rather than an informed selection based on research of their texts.
