Thing is, I don't see any post where MAB has directly accused anyone of anything. I think speaking of tendencies prevalent amongst large groups of people (and critics of Scn are, for our purposes, a large group of people. In fact, I think there're more critics than there are CofS members...the *cough* 8 million number notwithstanding) doesn't mean he's taking a poke at anyone or trying to be mean or level blame or any of that.
It's like the time I used the very common American colloquialism "here and there" and then I got three people jumping on me wanting proof of all the times I'd seen whatever it was happen on ESMB and why was I levelling blame. With one party, it was evidently a colloquialism with which he was unfamiliar. With the other two, they were people who viewed anything I ever posted with a jaundiced eye and they were reading something into it that just plain wasn't there.
Of course, I could be biased because I like MAB and always have. But I do know that when he wants to discuss a specific person, he does that. I don't view him as the sly innuendo type.
