"By 2010 about 157 countries and territories in the world had Christian majorities. [3]" (Wikipedia)
Brazil, Mexico, the Philippines, and the Congo are all over 90% Christian... that's over 425 million Christians who are not white, in just 4 countries.
I really hate this white, non white game, identifying peoples as whether they are white or not. Strictly speaking how white or non-white is Brazil? Hispanics are not white? I guess it depends. Many in the Latin world are whites from Europe who never really mixed with the aboriginals. How many or what percentage I don’t know.
