A couple days ago, commenter Pococurante took me to task, as he has in the past, for not banging the table against Hamas and Hezbollah when I write about Israel. And it kind of pissed me off, as I thought it was a dodge from the criticisms I offer of Israeli strategy. But now I’m having second thoughts.

During an unrelated email discussion with some friends, my pal Lindsay Beyerstein gave this a really great conceptual framework that I’m going to share with her permission. The specific subject we were discussing was whether the left in general is too quick to brush off criticism of some of the more illiberal practices in certain Islamic countries. Lindsay contended: “I think the left simply takes a lot of the most obvious criticisms as read. At a certain point, it feels gratuitous to spend much time badmouthing the Taliban’s version of Islam. Everyone already knows that they banned kites and gynecological exams and succored al Qaeda. What else is there to say? Nobody wastes time writing long nuanced critiques of Nazism, because it’s a self-evidently awful ideology.”

On the merits, I think Lindsay is right. But what if that’s because Lindsay and I generally agree on most things? How will this read to someone who doesn’t share a lot of our premises? That occurred to me after Josh Mull responded in comments to my Afghan-civilian-casualties post with the argument that he was taking the insurgency’s responsibility for killing civilians as a given — a given that I considered undue emphasis to a salient point.

The truth is, we all mark certain arguments or premises as-read, since it’s hard to write anything if you have to be explicit about all your given assumptions. But I want to thank Pococurante and Josh here, because they’ve pushed me to remember that not reader is going to share all of those premises; that not everyone who’s not persuaded as a result is unpersuadable; and that part — not all, not even most, but part — of a writer’s job is to persuade. I will try to write in the future with greater care against to falling into the rut that Pococurante highlighted, as it can only improve my work, and that’s a lesson that can benefit all of us, no matter what we believe.
