That phrase occurs in the subtitle of Javier Sanjinés's 2004 book Mestizaje Upside Down, a book about Bolivian cultural politics.* Cultural nationalism is a literary, aestheticized discourse. From the title of this book I also got the idea of "flipping" exceptionalism. I had already come up with the reversibility of the inferiority and superiority complex, and of progressive and reactionary versions of cultural exceptionalism.
Walter Benjamin famously said that Fascism aestheticized politics, and Marxism politicized art. Something like that, I believe in "The Work of Art in the Age of Mechanical Reproduction." That's true enough. So chiasmus is another master trope for cultural exceptionalism. Unamuno loved that trope, so he said instead of Europeanizing Spain, we should Hispanize Europe (for example). Now I'm remembering an essay by Thomas Mermall on Unamuno and chiasmus, in PMLA I think. Too late at night to look it up.
*I found this book first from a reference on Profacero's blog. It is a very good book and it is very good for me to read something so outside of my normal Peninsular expertise.
