[E]stablishing a fact is not the same as persuading others to accept that fact. The fact - the president is a liar - has long been established. Now, how do you get others to accept it? Say it: The president is a liar. Say it again: The president is a liar. And when someone demands proof, you repeat: The president is a liar.

Now, suppose they say, "But you've shown me no proof. That's just your opinion. Prove it." Now what? You say, "The president is liar."

Now to us liberals, this may appear at first to be a bit, how shall I say it, irrational and unfair. It is not. First of all, the person you are trying to convince is perfectly capable and in fact probably has read many of the same articles you have read, in which the lies of Bush are so painfully apparent. Their ability to reason is skewed, not their ability to read. Attempts to "set their reason straight" by advancing reasoned arguments merely reinforces the delusion.

The important thing to remember is that a deeply-held delusion is invested with deep emotional attachment. One's self-esteem, one's positive opinion of oneself, has become deliberately entertwined with maintaining that delusion at all costs. Dangerously so. It is that emotional attachment you must confront. When that has been dealt with, the ability to reason is freed to arrive at the obivious conclusion: The president is a liar.

Now in dealing with someone on the emotional level, there's no reason to be cruel, but you need to be firm. You need to weaken, in the face of enormous resistance, the emotional glue that binds the deluded to his/her delusion. You don't humiliate as in, "Schmuck! Any moron can see the president is lying through his teeth. WTF is wrong with you?" That further binds the delusion to the person's sense of self, which now feels attacked and therefore becomes defensive. Instead, you simply repeat, "The president is a liar."

Eventually, the repetition will permit the idea to seep enough into their consciousness to make the deluded start to wonder whether it is worthwhile investing their sense of self so deeply in someone who just may be, in fact, a liar. Your clue that this is happening is a change in the way the way the discourse is conducted. Instead of, "Oh yeah? Prove he's a liar!" you'll start to hear things like, "I guess he did cherrypick the intelligence a bit and in a sense, that's a lie. But you don't think Bush made stuff up out of whole cloth, do you?"

At which point, you respond, "The president is a liar" but, as Sean-Paul says, don't go into the details. Remember, they've already heard them but they can't reason about them properly yet and the problem they are having is emotional, not intellectual. They've started to wake up, but they are still entangling their own sense of integrity with Bush's.

It's only when they respond, "Okay, he's a liar. He lied and manipulated intelligence to get us into the war. But we have to support Bush now if we are not going to embolden the enemy" that you ease up slightly. You say, "The president is a liar. He lied to your face. Over and over. He lied to the soliders who are now fighting for their lives over there. The president is a liar. You owe him nothing. He owes you the truth."

Mass delusion on the scale we're seeing among Bush-supporters could, conceivably, be as difficult to break down as mass hysteria, but it seems reasonable to think that one way to go about it is to fritter away at the edges of the phenomenon, converting people one by one, and allowing the new meme to percolate inward at its own rate, while we follow along behind it, converting as we can.

Even though many of us have long since ceased to associate ourselves voluntarily with people so sadly deluded, it's a certainty that almost everyone has someone they can convert: a relative, an old friend, office mates. If done with care and empathy, a light touch, it might help.

Just think, a little over a year ago, Bush's approval rating, as evidenced in the 2004 election was just a hair over 50% -- now it's down to around 36%. That's a significant drop, but the biggest bloc of supporters that need to be turned are Republicans. Some are true believers, but surely not all, or even most of them.

Inroads can still be made.
