Two societies: One for the left, one for everyone else   

In leftist mythology, the world is composed of three groups: victims, oppressors and saviors. Most people in the world are victims.

The smallest group is the saviors who protect the victims from the evil oppressors.

The saviors are a small group of very bright, highly moral individuals constantly on guard against the uneducated and greedy hordes that would devour the world without their constant vigil.

This is one of the reasons that left-leaning scientists gravitate toward global-warming theories, and professors can't resist political correctness. They must save the rest of us from the rest of us, as long as "us" is not them.
