Deletion of Mighty 'white' of you

Comment: frankly do not believe the explanation absent a good |source citation. The expression itself was once common enough; "Not very white of you,"  "It was damn white of you," "This is certainly white of you," "Well, that's blamed white of you," Hopalong replied," "Darned if that ain't white of you, Parker!" Old Heck exclaimed," and "this is mighty white of you, do you know it? And after the way I guyed you when I first came in!" turn up in http://www.google.com/search?client=safari&rls=en&q=site:www.gutenberg.org+%22white+of+you%22&ie=UTF-8&oe=UTF-8 this Google search of Project Gutenberg. Don't think it's significant enough for an entire article
