Concerning the transformation of the State-sponsored Jamestown Commemoration into a diabtribe on Christian settlement, the New York Times explains:

...50 years ago, accompanying exhibitions were about Virginia’s British heritage and great achievements by Virginians. Now the theme is: “Three Cultures, One Century: America’s Story.” Jamestown becomes archetypal not because it laid the foundations for British influence on American political culture, eventually enshrining notions of rights and representation, but because it established a pattern of conflict with Indians and enslavement of Africans — something that is here homogenized into a more vague multicultural interaction.

...The Indians, we read, were “in harmony with the land that sustained them and formed an “advanced, complex society of families and tribes.” English society — the society that gave us the King James Bible and Shakespeare along with stirrings of democratic argument — is described as offering “limited opportunity” in which a “small elite” were landowners; in London, we are told, “life was difficult,” with social dislocation, low wages, unemployment, etc.
