Studying both sides, it falls on how you determine "white". 
Ask a Leftist if an American is white, they will say no, Americans were Red. 
Ask a Rightist if Americans are white they will say "hell yea". 
Ask a Leftist if Middle eastern people are white. They will generally break down the origin. 
Ask a Rightist if a Middle Eastern person is white, they will probably put a gun to your head and ask you why you are a friend of theirs. 
America is like anything else. It's a work in progress. Eventually Americans will realize that we all came from lands that were brutal to become free. Maybe even the freedom fighters will see that. . . . (doubt it)
