In “A Song of Ice and Fire”: EVERYTHING.
For Generation Xers Benioff and Weiss in “Game of Thrones”: The Sons of the Harpy are the insurgency in Iraq.
If you cannot get that Martin cares about Vietnam, you have not read a single word he has written in ALL of his books including “A Song of Ice and Fire” and said in interviews.
If you cannot get that Benioff and Weiss were writing about the insurgency in Iraq in “Game of Thrones”, you have not been listening to a word they said or watching the show.
It is not about Reconstruction because: 1) Martin cares about Vietnam, not Reconstruction; 2) the KKK do not present a force that creates a “heart in conflict with itself”.
You know nothing.
