Deleuze and Guattari discuss "the assemblage of relations that emerges from the destruction of 'the face,' [which] exposes 'faciality' as a system of signification and subjectification that works to anchor, classify, and control identity" (Kienle's summary)
I'm not totally sure that this is a groundbreaking insight on Deleuze and Guattari's part, but OK
"by demolishing the face, an artist destablizies the binaries on which faciality depends (white/Black, male/female, straight/gay, center/periphery) and reaches a polyvocal, multidimensional, and networked realm of being or becoming" (Kienle, 184)
