Conor Friedersdorf recoils from a blogger who views gay unions as "a relationship based upon a sexual act which can never rise above entertainment." Rod Dreher agrees with Conor on this point. (It's a garbled version of Robert P. George's and Benedict's attempt to dehumanize and delegitimize sex without reproduction). But Rod's deeper point - and the point of his favored blogger - is not against gays but against Christianists. He finds the Christianist politicization of deep moral questions inconsistent.
What Rod wants to recover, I think, is the pre-modern notion of obedience to religious authority and its interpretation of "nature" as a basis for modern civil society. It's a version of Alasdair Macintyre's hositility to modernity's philosophical incoherence. But Macintyre was smart enough to recognize that modernity was here to stay and to adopt a Benedictine option in response - of retreat from the world rather than an attempt to mold it in ways that simply will not work without coercion and cruelty and excessive government power.
And the difficulty of both embracing some parts of the modern world, while eschewing others, is evident in our current climate. That's why I favor a religious stance of distance from the world, rather than enmeshment in it and an attempt to control it. One critical thing Jesus taught was that controlling the world is not just impossible but inherently sinful. Our task as Christians is to control no one but ourselves and to love all. Our main weapon must always be example, not control.
