I don't know if this essay by John Holbo [link corrected] deconstructing David Frum's book is right, because I haven't read the book it attacks. (And, if truth be told, I'm especially unwilling to jump to conclusions because I used to know David Frum in college, long ago.) But I will say the Holbo essay is an elegant and very readable piece of writing in itself. Often people who write clearly think clearly too, so I'd bet that if it's wrong, then odds are it is wrong in an interesting way.
“Radical sartorauthoritarianism”? Gotta love it.
