The Left-Right model of modern politics has reigned long and unchallenged. Despite the fact that the paradigm is ill-defined and impossibly contradictory, people continue aligning themselves along a single, narrow line from the so-called “far left” to the so-called “far right.”
Just what do news reporters mean when they speak of “right wing Shiite militias”? Or when they refer to Putin's opponents alternately as “reformist leftists” and “the conservative (ex-communist) right wing”? Mostly, it is space-filling jabber, meant to gloss over the fact that the old model doesn't work, and never has.
