I find the best approach to a theist who believes that "without religion, we have no reason to be moral" is to just ask the guy/gal...
"Are you telling me the only reason you don't rape, steal, and murder is because you're frightened of god?"
"If the belief in god really is the only sufficient motivator for moral behavior, what do Atheists who don't rape, steal, and murder use in place of theistic belief?"
The statistical approach the guy in the video uses doesn't really matter, because the existence of at least one "moral" (in the eyes of a religious person) Atheist would be sufficient evidence that they're claim has been falsified.
---Why is buying homeless people food a moral action?---
If I were going to appeal statistically, I would look at the prison system...
"Fear of God doesn't seem to be a very sufficient motive when you look at the statics of inmates in federal prisons and contrast the percentage of theists and non-theists."
It works if you use the [Youtube] tag along with the full URL...
It converts it to a [flash] tag, just remember to close it!
