I've been describing this phenomenon, but this guy does it better than I could.

Rather than accept the reality of an enemy that cannot and therefore will not negotiate away what he believes to be the will of God, and rather than accept that this enemy will understand nothing outside total victory or total defeat, and rather than understand that this enemy’s goals include enslaving the entire world in a global caliphate, and rather than accept that this reality necessitates the use of all tools including military might to defend ourselves, millions have embraced an alternate reality.

The reality of the enemy outside the West and its motivations being too terrifying and too far beyond their own control, millions now imagine that the enemy in this war is within. The enemy, to them, isn’t the turbaned man behind the plot to hijack multiple airplanes and crash them into multiple buildings in America. The real enemy, to these millions, is the man in the Oval Office, and the man or men behind him.

Imagining the enemy as a Westerner who has a Western worldview and essentially Western motivations gives these millions the comfort of thinking that they can understand and defeat the enemy easily. They can expose him in the press or on their blog. They can spread the word through a bumper sticker or a sign in their yard. They can vote against him and encourage others to help vote him out. They can impeach him. They can shout and rail at anyone who supports him. They can destroy his political party and ruin his name. They can, in their own minds, win the war on their own terms without exposing themselves to danger. Because they have imagined their own enemy from before that day to be the enemy of civilization. And because it’s not really a war at all, just a made-up threat some evil neocons conjured up to scare everyone into giving them power. And that being the case, the deniers imagine that they can save civilization at the ballot box. They don’t have to find out what makes the enemy tick, they don’t have to fight him, and they don’t have to change their fundamental and now obviously flawed assumptions about humanity and the world.

If only it were that easy.
