Are conservatives paranoid?

Is conservative opposition to Obamacare rooted in paranoia and fearmongering?

David Bernstein at the Volokh Conspiracy says, "only a bit".

Various articles, such as this one, accuse conservatives of "paranoia" for thinking that health care "reform" will lead, for example, to Trig Palin being denied medical care. I agree that it's a bit paranoid, but not nearly as irrational as the critics suggest. Eugenics enforced by government dictate once had strong support on the Progressive left, more recently than some might imagine.

When African Americans express paranoia about the origins of the AIDS virus or the crack epidemic, sympathetic liberals explain that this paranoia is understandable given the Tuskegee experiments. Perhaps a little understanding of the paranoia that arises from the history of eugenics in this country would be in order. (And it's not like last Fall you didn't see various modern "progressives" writing some truly awful things about Palin's decision not to abort Trig!)
