You asked — What fiction?
—
I can only speak for myself on this one, but the one fiction that seems to persist in many places is that any people or any culture *deserves to exist* — apart from the recognition of the God of Abraham, Isaac and Jacob (from that nation and/or culture) as an *integral part* of that same culture and society.
Short of that they *do not deserve to continue*... that would be one fiction... that I can think of...
[... and I don’t exclude current-day USA from that one either...]
