You cited your opinion that the policy supports Woodrow Wilson instead of his actual name including the first name. I base myself on no other policy but hold a different opinion.
PS. Your disagreement (posted on the talk page) is now noted as opposed to before, when I had not seen your comment there and only had your edit summary which didn't bring a substantial opposition but only talked about a lack of consensus.
BTW, any further discussion should be on the talk page and not on user talk pages.  (talk)
