LOL. YOU started the edit war. A well-meaning user (who has not even participated in the discussion so far) has added a tunnel=culvert tag. You have reverted the addition (removing valid information). This is the start of the revert war.

And how has it turned into a revert war? The community has discussed your revert on IRC/Matrix and decided that the tag should be readded, and has done so. You have repeatedly reverted the addition. I count 4 consecutive reverts from the same user (you) of edits by 3 different users, all on the exact same issue.

And then you have the nerves to accuse others of having started an edit war? You cannot be serious!

> The tunnel=* tag in your example was set by an armchair mapper who had never been there.

Even disregarding the fact that this accusation is probably not accurate in that case, you need to get rid of your pathological disdain for "armchair mappers". A lot of useful work in OSM is done by armchair mappers, considering all the freely licensed data sources out there nowadays (OGD etc.). I would even guess that MOST useful contributions to OSM come from "armchair mappers" nowadays. It does not scale to go personally to every object whose tagging needs to be completed and/or corrected. All the more if it is not necessary, because the disagreement is about how a feature whose appearance is NOT disputed should be tagged.
