My mother once told me that all morality originates from AA. She was dead serious. There's a story, confirmed by several witnesses including, I think, an impartial journalist about a guy in Straight thanking Group for causing nerve damage so severe that he permanently lost the use of his left arm. He said it saved his life. He was dead serious too.
Yes, group-think is incredibly potent stuff.
What experiences and history teach is this-that people and government never have learned anything from history, or acted on principles deduced from it.
--G.W.F Hegel (1770-1831)
