That's an interesting google with interesting reads But how to deal with all those people in the environment, who are dead sure about it. Not only the active prophets, but also maybe ones siblings and children are among the quiet or vocal believers. You can't just remove those from you life, because of the fundamental disagreement. I read that on 22 December none of the believers will be elated that we're still there, thankful to those who kept the world running. They'll invent just a new End-of-the-World-as-we-know-it. So what are the socialogical/psychological 'forces' behind that apocalypsm and what can we do about it?
