My former colleague, the moral philosopher and former editor of Ethics, John Deigh (Texas) wrote:

I regret that so many…are unable to separate your private email correspondence from your editing the PGR and to see that what's deplorable in all this is the behavior of the two individuals who made public, without your consent and with the intention of harming you, private correspondence you sent them.  That this behavior was called by one of your detractors courageous is mind-boggling.  Both individuals are full professors with tenure at well-respected research universities.  What possible danger to their professional standing could they be in from having earned your scorn?  Academic highmindedness at its worst.  

I've heard from a lot of philosophers who have the same view, and I'm grateful to John for permission to quote him.
