For the record, there exists a book that will make you question your Christianity. It's not by any famous atheist or anything, it's actually by a self-proclaimed "god believer" who's just a christian who is trying to trick people into thinking he's not. Though he's so fucking insane that there's no way to be totally sure he believes anything he says. But this fucking book, man. It's insane. Like I would literally burst into flames if I tried to read it.
