Religion, by its very nature as an untestable belief in undetectable beings and an unknowable afterlife, disables our reality checks. It ends the conversation. It cuts off inquiry: not only factual inquiry, but moral inquiry. Because God's law trumps human law, people who think they're obeying God can easily get cut off from their own moral instincts. And these moral contortions don't always lie in the realm of theological game-playing. They can have real-world consequences: from genocide to infanticide, from honor killings to abandoned gay children, from burned witches to battered wives to blown-up buildings.
