"just stating a fact, a fact that is obvious on every thread."

As I don't post on anything like every thread, it can't possibly be obvious on every thread. Also, as I post to threads that are entirely non-controversial, such as the 2015 joke thread for example to name but one, your stricture would not apply in those cases. As I have often corrected myself or apologised for something I've said, to stand corrected is not an alien concept to me at all. As usual, you think you have a monopoly on the truth and that anyone who disagrees with you is wrong. As one of the people here who have the most to apologise for or correct themselves over, it ill behoves you to level that particular criticism at anyone else.
