Seriously, Roger Ebert makes a lot of sense when he wades into the political pool and his teabagger analysis does him credit.

How much of the anti-Obama outrage is racist? Some is. Many of these angry people (I believe, but cannot prove) are made deeply unhappy by the reality of an African-American in the White House. Let’s not pretend otherwise. Perform this mind experiment. If Obama had declared war in Iraq and was caught lying about weapons of mass destruction, what would the right have had to say?

Racism plays a role, but conspiracy theories themselves have an addictive quality. They appeal to a personality type. Many of those who take nourishment from them have, I suspect, a bitter resentment against authority. They don’t want anyone telling them what to do. They’re defiant. Some of them may have been the victims of child abuse. Anyone who is in power is lying to them for evil motives. Nothing they learn from the mainstream media can be trusted. Some people may think they’re so smart — but these conspiracy insiders know the real story. They learn it from each other, they embellish it, they pass it around, they “document” it with invented connections, they bond among themselves, and they live in a closed system that seems to validate them.

They lack common sense. Their conspiracy theories cannot tolerate it. Most reasonable people, when they heard Obama wanted it kill their grandmother, simply smiled, because — well, because they knew he didn’t. But the conspiracy people Know Better. That’s the whole point. That’s where the fun comes in. They have a peculiar intensity in their circular reasoning. They cite facts that are not facts, supported by authorities who are not authorities. As my grandmother freely said of perhaps too many people, “They don’t have the sense God gave them.”
