“In my study of communist societies, I came to the conclusion that the purpose of communist propaganda was not to persuade or convince, not to inform, but to humiliate; and therefore, the less it corresponded to reality the better. When people are forced to remain silent when they are being told the most obvious lies, or even worse when they are forced to repeat the lies themselves, they lose once and for all their sense of probity. To assent to obvious lies is in some small way to become evil oneself. One’s standing to resist anything is thus eroded, and even destroyed. A society of emasculated liars is easy to control.” – Theodore Dalrymple
All I would add is that it’s not just communist societies. This is not primarily a political blog, however, and I’m not really interesting in starting fights, so I’ll leave the identification of specific examples as an exercise for the reader.
