Im a bit distracted right now but I agree that the situation here does not look good When an edit war starts over tags on a featured article you can pretty much assume that nothing productive is going to emerge I was about to suggest that  the tags be dropped as a distraction as well as being a bit pointy when placed on a recently featured article  that only edits that improve readability be done on the article without discussion  that the purpose of other edits ie how specifically they improve the article very very specifically be listed on the talk page before the changes are made any discussion from this will help all parties if mediation becomes necessary And finally I wanted to point out that while there is no bar on editing a featured page TalkIndia for example encourages editors to be WPBOLD and improve the article all this be done in the spirit of good faith I see very little assumption of good faith on either side and a lot of heated rhetoric
