Sarah Posner's concluding sentence in that post is, "When you wave a Bible in someone's face, just remember that someone can wave one in yours, too."

I'm not much for literal Bible-waving, myself. But the Christian Right isn't going to stop waving their Bibles figuratively and literally in the faces of Democrats and mainstream Christians. And there has to be pushback in moral and religious terms to disrupt those messages.

What's wrong with liberals agreeing with Wallis on Medicare and disagreeing with him on women's rights? People can make moral, religious and practical arguments on the liberal side of both issues.

Honest religious arguments have their limits, because any honest believer would have a problem claiming that they knew for sure how God would want them to vote on a particular legislative bill or political candidate. But the Christian Right aren't making honest religious arguments when they lie to young women in their fake "pregnancy counseling" clinics about abortion. They're just lying to people who made the mistake of trusting them for honest medical advice. The public policy on how to deal with that kind of fraud may be complicated. But I have no trouble arguing on moral and religious grounds that that's just wrong.

And since the fundis are going to keep making their arguments in the "public square" (as they like to call it), I don't see how either secular liberals or Christians who don't support hate-mongering or torture or lying to pregnant teenagers in the name of Jesus can just avoid trying to counter the religious elements of those arguments. People can make religious arguments for or against a policy like the water torture, aka, waterboarding, without insisting on it as a purely religious policy.
