Actually, you've got that exactly backwards. It is an idea that -- outside of very small groups, anyway -- cannot be translated into a way of life.
(Denny Crane: "I Don't Want To Socialize With A Pinko Liberal Democrat Commie.Say What You Like About Republicans. We Stick To Our Convictions. Even When We Know We're Dead Wrong.")
I disagree. Communism translates easily and consistently into a 'way of life.' It's just that the actual way of life to which it translates is 180 degrees different than the way of life it professes to bring about.
