Recently, I absorbed Arjun Appadurai's little book "Fear of Small Numbers" (http://www.dukeupress.edu/books.php3?isbn=3863-7) which he frames as a deliberate contrast to the "Huntington model" from Clash of Civilizations.
There are some good concepts in here:
1. The notion of "predatory identities" which is to say identities that cannot exist without eliminating other identities. I would extend this concept to "parasitic identities" as well, with obvious implications.
2. The idea that the respect of minority groups in liberalism has always been tied to the fear of "dissent" and not the respect for difference.
3. The need for a shift in thinking from the "clash of civilizations" (Huntington) to a "civilization of clashes." I think this has important and useful implications related to agonism in general.
It dovetails nicely with Laclau and Mouffe's articulations in "Hegemony and Socialist Strategy," as well as Hardt and Negri's "Multitude."
It's pretty clear he's talking about panarchy:
"The new transnational activisms... build their actual solidarities in a more ad hoc, inductive and context-sensitive manner.... coordinating without massive centralization, reproducing without a clear-cut mandate, working occasionally in the larger public eye but often outside it, leveraging resources from state and market to their own ends, and pursuing visions of equity an daccess that do not fit many twentieth century models either of development or of democracy." (p136-7)
