Henry Farrell takes some time to write a careful case that he summarizes thusly:

Megan McArdle believes that we would all benefit from more intellectual charity in the exciting cut and thrust of the blogosphere. There is indeed a plausible case for this. What there is not a plausible case for, in my opinion, is more intellectual charity towards Megan McArdle.

This case begins with a discussion of the infamous “spanking Eric Rauchway incident,” which you may remember concluded with Brad DeLong and Paul Krugman saying I was right. Henry says McArdle promised to revisit the issue, which was a promise I did not see at the time.
