"Q1. Have I been involved in the edit war?

A1. Yes --> don't protect the page, and it's probably best to let the
other person win for today to end the edit war, and if the remaining
participants keep having an edit war, ask another uninvolved sysop
to protect the page."

*I had never edited the page prior to this edit war and I have never added content to the page. The article's history demonstrates that I only restored versions, which were to be protected, that did not contain the content responsible for the edit wars. Personally, I was the ideal person to stabilize the page, being of no faith and never having participated in topics pertaining to the sex-abuse scandal. I have not contributed a word to the article.

A2. No --> protect the page, proceed to Q2.

Q2. Is there some edit that needs to be urgently made to fix the
page, or is there some very cautious thing I could do that's likely
to help for now?

*Yes, there was an urgent need to edit the page. Due to Nostrum's repeated refusals to cooperate with the other contributors, I was forced to restore the latest version not to include the unacceptable content.

A2. Cautiously make the edit.

*And that's what I did until Eric overreacted, probably unaware at the time that I was not involved in the edit war, have never expressed any strong feelings about the subject, had been asked to protect the page, have read requests to protect the page, waited cautiously while the article was stable before protecting the page, warning all involved contributors that I'd be willing to protect the page, and finally unaware of the unacceptable quality of the text.
