What makes you think I stopped reading? How do you think I knew that he was attacking a straw man (and hence making a fool of himself)?

Well, that's nice. I feel vindicated. But that doesn't change the fact that he published a totally unwarranted ad hominem attack directed at me based on incomplete information and never retracted it, let alone apologized for it. (Sorry, but a comment doesn't count. Most people don't read the comments.) So I stand by my position that his behavior was unprofessional to say the least.
