Mayberry Machiavelli

Mayberry Machiavelli (plural Mayberry Machiavellis)
(pejorative) A person who furthers his cause by "reducing every issue to its simplest, black-and-white terms for public consumption", i.e., denying nuance by using stark, but false, choices. For example, if you did not support the Iraq war, you were a Saddam Hussein supporter.
