Daniel, you don't take those idiots more seriously, than, say islamic clerics waging a holy war against the "west, do you? Their sole role is to act Rush Limbaugh - babbling nonsense with one and only one goal in mind - smearing the "bleeding heart liberals" by any means necessary.
I stopped considering economics a science long time ago. At its best it is metaphysics, a relatively coherent system of beliefs how things ought to be according to the tenets of the rat-choice creed, but telling little how empirical world actually works. More often, however, it is a jihad against political enemies of the ruling elites waged by a bunch of half-witted sycophantic journalists and pundits who do not know, or pretend not to know, what they are babbling about and claiming that market-schmarket will perform social miracles - even in the areas where its more knowledgeable adocates see a potential for an almost certain market failure (e.g. public goods or high infromation asymmetry).
