Moderator's note: too often the moderators have to speak up when a thread is going sour, and I just want to speak up here to say that I was fairly blown away by this gracious response. And it would not have been possible without the temperate rebuttal to which you responded. Kudos all around. I may hold this instance up as a model for others. Of course, not every rebuttal is going to convince. But the odds increase, to maybe 5% instead of zero, when you state your case with respect. Here endeth the sermon.
