What is best for the article is probably best left to the regulars who edit this page to decide. I'll lift the protection for now. If reversions start creeping in regarding that particular phrase, I'll be inclined to protect again. The intensity of the reversions suggests to me that a rewording might be necessary (but not necessarily so). For something like this, providing a reason for reverting only in the edit summary is insufficient. If the phrase should really be there, I would suggest that a post regarding that phrase should be made on this talk page - this is just another way of reaching out to the anoymous user. As suggested below, if that particular editor is sincere, they would participate in rational discussion here. Otherwise, I suppose the edits can be treated as you did before. I hope this helps moving forward.
