For what it's worth, Meursault, you seem to have misinterpreted that thread, although to be fair it's not too surprising. I was actually complaining about the threads being deleted far more than I was about you posting in them. It seemed to me that there was no reason for the second thread in particular to have been removed. You had posted in it, nothing particularly unreasonable from what I recall, but it vanished anyway. So, in fact, I was complaining about what appeared to be overzealous moderating.
Yes, I suppose my thread implicates you as the cause, but I think that's fair enough. You resurrected the debate. You then continued it into a pair of other threads (and, for that matter, this one), even after it was clear that your arguments weren't going to be taken on board. At the very least that makes your contribution the catalyst for what followed.
If you checked later in the thread you're referring to, you'll see that I (and others) have even accepted some of your points: "... perhaps Meursault has even done us all a favour", I said; also "[Meursault has made] a reasonable point that a public forum is a public forum". I even took the trouble of coming over here, mainly for the reason that it seemed clear that a discussion at all was impossible at AB. Had you made your point and left it at that, without helping to bring it to a personal level, maybe none of this would have happened.
Solely responsible? No. Responsible to a large extent? I know my opinion on that.
No apology is necessary, though. You have your opinion of me, and I've long since gone past caring what strangers on the internet think of me. I hope I've been reasonable here, at least.
