I don't need to cite anything, look at how it happened in practice. But I forgot, you claim that was not "genuine" practice. Oh well. Nothing was. The thing remains an utopia, and people will continue to be cheated by ideologists. Hence the instinctive disgust for a pragmatic, rational approach, not unlike creationists' when you bring them to carbon-dated samples.

Free at last! Free at last! Thank God Almighty, we are free at last! (Martin Luther King)
