As noted above " an editor who is involved in a significant off-wiki controversy or dispute with another individual, or who is an avowed rival of that individual, should not edit that person's biography or other material about that person, given the possible conflict of interest." I am concerned that semantics are being engaged to deliberately distort the article for political gain, and that a conflict of interest is impeding the process. Unless you are willing to stand aside, I can see no alternative than to take the matter to the WP:BLPN notice board, in order to seek arbitration on the matter. (  )
