Negation is a form of identity politics... perhaps the most prevalent form of it. The reason the hegemon will rail against identity politics is because it no longer allows them to us negation.

It is a pernicious mask because it has a sense of fairness to it that is, however spurious, attractive to those on the left who might wish to consider themselves fair-minded. The term itself, ‘color blind’ arrived in the blistering dissent to the manifestly awful Plessy v Ferguson authored by the Associate Justice John Marshall Harlan, himself a scion of a prominent slave-holding family in antebellum Kentucky.
