Users are cautioned to assume good faith, and to recall that all new users must start off somewhere. Further, many people with expertise in a specific area quite reasonably make contributions within that area alone.

There is, of course, nothing inherently wrong with single-purpose accounts (Wiki discussion policy cautions against personal criticism).

If you are going to assume the mantle of editorial arbitor and enforcer, then it is your responsibilty to ensure the article is accurate.  Controversial subjects are by definition controversial.  That is the nature of Paul Wolfowitz.  The article as presently edited is biased in two respects:  a) through its uncited inclusions, including the one noted above and b) through its omissions.  There is a direct relationship between Wolfowitz's 2001 departure from SAIS and his 2007 removal from the World Bank.  Readers would not gain that information the way the article is currently presented.  You are invited take the factual material that you deleted and to conform it, but there needs to be a context to the section entitled "Recent Controversies."
