No one has all the answers when it comes to questions like this. If you believe you do, you scare me. Moral authority and questions of morality are ones that require some deep thought. I believe some of the basic answers are simple but there are plenty of gray areas for debate where we may never have a solid answer.
If you think The Littlest Atheist is down and out stay tuned as he faces the Lake of Fire (or rather the baptismal pool turned into a lake of fire).
