Jonah’s anthology of e-mails includes the following: “Markets are about choices, not about mandated diversity. Mike would seem to be hoping for a series of (using the market metaphor) state-financed enterprises to provide make-work for those who simply cannot compete.” I am delighted because, in America, any kook who wants to is allowed to spout his opinions . . . and this means I’m somehow in favor of “mandating” something “state-sponsored”? The exact opposite is true: I defend the right of people to say things I disagree with-that doesn’t mean I favor the creation of previously non-existent opinions that aren’t actually held by anyone. There’s enough diversity among existing opinions. (In any case, a government program to support diversity would work about as well as most government programs, and we’d actually end up with less diversity.)
