This seems right, unfortunately
Polizeros quotes Slavoj Zizek:

A will to ignorance suggests a troubled conscience: if our government kills and improverishes people to maintain a global hierarchy, Americans don't want to hear about it because it hurts.

It's not just a matter of getting the facts out there. The will to ignorance is too tenacious for that, and there's no master key in existence that will unlock it. But the first step in devising such a key is to admit one is needed. Facts alone won't do the trick.

It's true. Lots of people like being ignorant. They're proud of it. They probably like Bush because he's one of them.
