I refer to this post, by Dan, which is fairly typical of fundamentalists. The common thread is that fundamentalists will say that “atheists” do not have a reason to believe that murder, rape, theft, etc. are wrong. It’s not that “atheists” don’t have reasons. They do. But the foundation of those reasons is empathy and compassion. And these traits are foreign to fundamentalists. Fundamentalists, being psychopaths, can only understand self-interest. They don’t care about anybody else. To them, a reason must rely on an “authority” with a big club to enforce his will.
