I was prepared Moderator would lock that particular thread. It was therefore that in my last short post (three of four lines) I have exercised extreme care to be as polite as possible, so that nobody could ever feel offensed. Moderator has locked the thread nonetheless. Why? One can only guess, but seen the circumstance that in my last polite post was the evidence, one cannot rule out moderator has judged me presenting the evidence, not welcome.
