Ok, what is the difference between Stalinist Russia and post-WW2 Sweden? Both are left. Is Sweden "moderate" left? And thus more "right"? Because you can't get more economic "left" than Communist Russia, can you? Then again, an absolutist government like Stalin's is actually more something you'd attribute to the "far right", along with the leader cult and all. Not unlike Hitler, Franco or Mao. No wait, that last one was "left", right? Where does Gandhi fit into it all? Is he "left"? Where would the likes of ISIS be located? Right wing? They would sure fit the anti-democratic, conservative picture, in the most extreme way. But they didn't strike me as the economic laissez-faire type. So are they left? Where do they fit in?
Politics is way more complicated than a simple binary system could represent.
