I'm not the "Ugly American" (for those that read the book) or the Jimmy Carter (for those that idolize him) who, while not being a missionary sent on a mission, instead launches a Crusade upon a foreign country's government by reason of my American church and American religion.  I think England did that once upon a time and its scion, the U.S., followed suit with Iraq and other creatively modern ways.   While you separate church from your own government, you won't separate your church or religion from imposition upon a foreign GOVERNMENT.  Rather than resign yourself as a pedestrian missionary allowing Caesar to be his own Caesar, you as the tourist would be the Caesar.  You will be that Ugly American.
