Thanks for this sanity reminder, Bogdan. I myself added the following template to the top of this Talk page just a few days ago: "Remember that article talk pages are provided to coordinate the article's improvement, not for engaging in discussion for discussion's sake. Do not use them as a discussion forum." What this means is that we can not censor MarkStreet or anyone else because of their opinions, or ask them to shut up. But we can (and should) ask everyone, including MarkStreet, to only comment on issues which are relevant to editing the main article: Edit suggestions, sources, etc.
 PS: I just archived the 300K-long Talk page, as Archive 7. I kept topics open where we still have some pending issues to take care of, in advance of the protection being lifted. -
