Seriously? Morally white?
That is as racist as those people who used to use the phrase "that was white of you" as a compliment.
Which "morally white" would that be?
Would that be like St. Francis of Assisi 'white'
Madonna 'white'?
Adolf Hitler 'white'?
What does that crap even mean? Except as a racial pejorative, I see no meaning to the phrase.
