Or, for a sadder experience, there's the children of whatstheharm:
The site features such horrendous stories as that of 9-month-old Allyson Bergmann of Indiana
Allyson contracted bacterial meningitis which is medically treatable. Her parents belong to Faith Assembly, which rejects medical care in favor of prayer. Allyson's disease went untreated by anything other than prayer until she died. Her parents were convicted of reckless homicide.
Unfortunately, Allyson's case represents the norm rather than the extreme of the stories on whatstheharm. It just goes to show how much harm is done when people and society are incapable of critical thinking. And people claim that it is the atheists who are the ones without morals.
