Read it and be enlightened. The good Professor Knippenberg correctly points out that having religious reasons for pushing a particular policy is quite different from enacting a religious law.
As the professorial pundit puts it:
Yes, the FRC and Focus on the Family are religious groups. But what they are asking for is an up-or-down vote on judicial nominees, not a religious test for office-holding. Whatever faith or reasons move them, the position they’re actually supporting is consistent with long-standing Senate practice (actually voting on nominees). Yes, there’s a slippery slope somewhere, and the judiciary may be the only remaining bastion of secular liberalism, but the alternative is not theocracy, but rather sober constitutional jurisprudence.
The distinction is frequently lost on journos who have studied little more than how to write crisp paragraphs. Lefties conveniently forget their outrage over incursions into the secular realm when the religious conclusions are other than conservative or free market. See my AmSpec piece on an interesting situation in Alabama last year.
