So my answer to this question got edited in a way that I didn't intend, and as normal I rolled it back. The edit got repeated, so I rolled it back again and was about to point out to the offender that this wasn't permitted by the rules of the site to repeat an edit that has been rejected by the author, when the perpetrator added a comment saying that they were a mod. They then locked the answer with their version of the edit conflict in place.
I respect the mod's right to a personal opinion on what I wrote, but I don't think it's appropriate to force those opinions on others, or to use mod powers to resolve an edit conflict in their favour. Nobody else had complained about the answer, and it's heavily upvoted. There was something the mod's comment about this "descending into a bunch of arguing", which I hadn't noticed, but I'm fine with the mods removing argumentative comments.
