I love this idea but I'd like to see it as Religion vs Secularism. One tribe is all devoutly religious people, The Zealots, like Leslie and the other tribe is strictly Atheists. I don't mean atheists as in, "I'm too lazy to go to church except for xmas midnight mass", I'm talking about hard core "there is no god" atheists.

The fun would never end. The Atheists would win every challenge using logic while the Zealots were praying for a sign of what the puzzle is supposed to mean. They could have an Outcast Island and the fun would be to see if anyone was converted (either way.)

The Atheists would never go to tribal council because they would never lose a challenge and, when The Zealots went to tribal council (which they would refuse to do because it sounded "pagan") the person voted off would be stoned to death as well.

Jeff should take the season off and celebrity host Tom Cruise could laugh at all of them and offer to trade the million dollars that the winner would receive for a chance to get to OT Level IX and a personal audience with LRH.

That would be awesome (am I going to hell for this post? Oh, wait, it doesn't exist. Whew!)
