Hawkins does not argue that these statements are false that e.g. Glenn Beck is not a crank. His point is that regardless of truth, these criticisms should not occur. Or anyway, that no conservative should engage in them. Our job is to fall into line and not notice that Beck is in fact a crank or that Palin is not well-informed or that the Tea Party has saddled the Republicans with awful and probably doomed candidates like Sharron Angle and Rand Paul.
Hawkins’ attitude here reminds me of an ancient definition of a political party: “It doesn’t matter what damn lie we tell, so long as we all tell the same damn lie.”
