I don't mean to take sides here, but I think we are talking about a powerful form of expression called allegory.
The representation of abstract ideas or principles by characters, figures, or events in narrative, dramatic, or pictorial form; an extended metaphor.
A story, picture, or play employing such representation. John Bunyan's Pilgrim's Progress and Herman Melville's Moby Dick are allegories.
A symbolic representation: The blindfolded figure with scales is an allegory of justice.
Allegory: used only in Gal. 4:24, where the apostle refers to the history of Isaac the free-born, and Ishmael the slave-born, and makes use of it allegorically. Every parable is an allegory. Nathan (2 Sam. 12:1-4) addresses David in an allegorical narrative. In the eightieth Psalm there is a beautiful allegory: "Thou broughtest a vine out of Egypt," etc. In Eccl. 12:2-6, there is a striking allegorical description of old age.
Darn. More research.
Oh, so purloined work and fiction claimed as factual history is now " an extended metaphor"? Not in this universe, it isn't...unless in real life, you are Ward Churchill! Ward, is that you, you lying, wannabe Indian ?
Instead of trying to make excuses for him/your other nic, stay out of this battle.
