"That's mean talk that I shouldn't use about anyone, and I'm sorry." He's saying that after "reflection, and in response to a torrent of near- identically phrased outraged mail...."
Not much of a backtrack. Here's where we talked about him yesterday. I don't know if I'm responsible for any or much of his "outraged mail," but if you feel like going over there now and telling him off, please word your email in a manner that displays the unique person that is you.
