Why African can not accept monotheism spirit-God and Jesus Christ

Why African can not accept monotheism spirit-God and Jesus Christ.  The fact is, the Puritans were the forerunners of today's Kingdom/Dominion/Reconstructionist teaching. The Puritans believed that they were carrying to America true Christianity as decreed by God, especially as written in the Old Testament. They believed too that they were on a divine mission to America, a place specially appointed by God to be the "New Israel," a theocratic "city upon a hill."  ---The Puritans viewed themselves as God's special people, replacing national Israel. Nowhere do the dangers of this assumption become more clear than in the Puritans' treatment of the native Americans. Since the Puritans considered themselves God's chosen people, they concluded that they had the right to take the land from the heathen Indians. The American Indians were the "new Canaanites" in America's "Promised Land." The fruit of Puritan theology was brutal. They saw their mission as convert these "Canaanites" to Christianity; failing that, it was acceptable to slaughter them in the name of Christ.
