Update: if anyone had any doubt about my opinion, the following PM “conversation” (really train wreck is more like it) might also be enlightening. I am aware that this was supposed to be private chat, but I believe that there is no room for misinterpretation here, and so I feel that my action is justified in the interest of general awareness. If anyone feels I am crossing a line by airing this, downvote at will; I shall stand by my decision.
