Thanks for posting that. It makes a great deal of sense.
3) Liberals see people who disagree as evil:
"To understand the workings of American politics, you have to understand this fundamental law: Conservatives think liberals are stupid. Liberals think conservatives are evil." - Charles Krauthammer
#3 is true and important to understand about liberals/Progressives. On my profile page is an essay I wrote about fanaticism which is about that. It may not be a great piece of writing but it is my attempt to describe why liberals and Muslims act the way they do and why they are dangerous. But they are predictable in some respect.
As he often does, Charles Krauthammer encapsulates the whole thing in one clear sentence.
