Jonathan Weiler in the Gadflyer explains why real conservatives should fear the Bushites just as much as liberals do. He talks about the traditional conservative critique of utopianism on the left:

Human fallibility, conservatives argued, transformed the arrogance of social engineering into pernicious unintended consequences, upending routinized ways of living and disrupting human communities for the sake of some edenic abstraction. Conservatives viewed such thinking as millenarian, childish and fatally reckless.

What’s remarkable is how un self-consciously the American Right have become the radical social engineers of the new century, both in their vision for re-making the world order and in their desire to dismantle by-now universally accepted American institutions, like Social Security.

No place in the world currently more starkly represents the insane designs of the new global social engineers than Iraq. The recent evidence, of at least 100,000 excess deaths in the first 18 months of war, gives a sense of the impact of that arrogance on the basic functioning of human communities in Iraq. And, remember, when the evidence refers to excess deaths, it refers to deaths over and above what would have been expected had previous conditions prevailed. In other words, America’s new liberationist fanatics have visited 100,000 excess deaths on top of what likely would have prevailed in a regime still run by a murderous tyrant presiding over a barely functioning economy. Iraq is the most comprehensive dress rehearsal to date of the combined hopelessly simpleminded and utopian visions of free markets and neo-conservative fantasies of imposing freedom by force.

For obvious historical and political reasons, it was easy in the United States to criticize Marxism in toto. Just as obviously, attacking a singular Chistianity in America is not politically viable or strategically wise, nor would it be fair to do so. But, as others on this site have been pointing out, especially since the November elections, it is critical to make clear the character of a particular brand of millenarian Christianity, now being cross-pollinated with an unabashed effort at global domination as pushed by neo-conservatism to create a new super-strain of utopian transformationism.

Combined with the millennialism of Dobsonian and Fallwellian Christianity, we stand in the grip of a new pathological worldview. This, it should be clear, is not only a concern for liberals. It should also exercise the minds of cold war conservatives ... It’s important for us to see this new super strain for what it is – a mortal challenge to bedrock American institutions and a fundamental threat to world peace.
