It's not ad hominem -- I'm not saying he's wrong because he's a coward. I'm saying if you're going to be so judgmental and flippant about a process you probably have never been involved with, and also so personal as to call out a person by name for their own decisions, don't be cowardly when you do it.

He could have very well-placed criticisms actually, I don't make any assessment one way or the other as to that question.

Bottom line -- the guy wants to hold PG accountable to some imaginary (but popular) standard, while evading accountability himself.
