Andrew, if this is what you're talking about, I can assure you that you've never seen me when I'm making a serious ad hominem attack:
My post #450 to VadeRetro:I was most definitely criticizing your analytical technique here, which is sometimes good, but too often mere fly-specking; however I've said nothing negative about your character, your veracity, your sincerity, or your intelligence. Not ever.
AndrewC has the natural abilities that would make him an excellent proof-reader. But fly-specking, although a necessary task, isn't the same thing as making a substantive review, and it certainly doesn't constitute a rebuttal.
Absolutely true, and I appreciate that and laud you for your approach, however an ad hominem as far as an argument is concerned is not necessarily negative.
