Liberal democracies have good reasons not to organize themselves around a series of ever-proliferating identity groups inaccessible to outsiders. The dynamic of identity politics is to stimulate more of the same, as identity groups begin to see one another as threats. Unlike fights over economic resources, identity claims are usually nonnegotiable: rights to social recognition based on race, ethnicity, or gender are based on fixed biological characteristics and cannot be traded for other goods or abridged in any way.
