Paranyms.

"Zealotry is rich in paranyms. A paranym is a word used as an evasion, often in a sense that is opposite to its actual meaning: liberate for conquer, liberal for authoritarian etc. Zealots like to change the vocabulary in this way and paradox is one of their victims. Time and time again reality diverges from the dogma, so there has come to be, for example, the obesity paradox. Never mind though, for one of the first principles of zealotry is to ignore any contrary evidence. Another of their favourite techniques is to exploit the end-point fallacy. In Britain, for example, they almost invariably choose the fifties as a point of reference, a time when British women had suffered more than a decade of starvation. In America obesity rates have not changed for seven years, but are still routinely portrayed as a growing crisis. Over and over again the obesity scam is exposed, but the campaigners simply ignore the contrary evidence and march on".

[My favourite was always the fact that any state which was emphatically totalitarian would describe itself as a 'democratic republic'.]

I STRONGLY recommend that you read the whole article! John Brignell seems to know what he is talking about.
