@Shawn: You're entitled to disagree. In my experience with people, their beliefs are something they are willing to make and lose friends over. Start and lose a job over. As with Witnesses, devout Catholics, Davidians, Baptists, Jews, etc., people are willing to die and/or kill for those beliefs.
The bible is riddled with account after account of people mudering and slaughtering in the name of their beliefs.
Clearest example: if you're an atheist, and the United States government said you HAD to worship the Abrahamic god or go to jail. This means going at least three days a week to church.
You going to stay quiet? The VERY moment you complain about it, you prove the idea "you're beliefs are your life." Cuz if they aren't why would you complain about someone ordering you to believe something else?
Those robots in the Kingdom Halls, their belief is their life. Doesn't mean it's a good or bad belief. Just means what they believe is their life.
Another example: if you knew there was no heaven or hell, no paradise, would it change the path you take in life? If you couldn't be punished after death for your actions, wouldn't you live a little more?
It's not a bold statement I'm making here. It's just common sense.
