Jonah the Fool
Poor boy. He's decided that liberalism is a "secular religion," then is frustrated that this "religion" that he's conjured up in his imagination lacks sacred texts that he can analyze. As is so often the case with his kind, he is unable to draw an analogy between those who are liberal and those who are conservative. Though conservatives' political views may be guided in part by their religious beliefs, something he no doubt knows, he is blind to the notion that the same can apply to liberals. Because the religious beliefs of liberals lead them to view life and politics differently than do those of conservatives, Goldberg concludes that these religious beliefs aren't valid, that liberals lack a religion other than the undefined and illegitimate "secular religion" he has chosen to assign to them. And, of course, because this "religion" doesn't really exist except in Jonah's overanxious imagination, it lacks a sacred text, a Torah, a Bible, a Koran, that he could pore over to see if the religion's practitioners are abiding by it. Yes, poor boy.
This pretty well sums up the worldview of Republicans, doesn't it; they become vexed when the fog clears enough to reveal to them that there is no evidence to support their make-believe world. They then curse reality, rather than adjusting their perception.
