Bisexualitatea, gizarte postmodernoko indarrik desestabilizatzaile handienetako bat:
"Bisexuality means that your sexual identity may not be fixed in the womb, or at age two, or five"; it "unsettles ideas about priority, singularity, truthfulness, and identity". "Bisexuality presents "the radically discontinuous possibility of a sexual 'identity' that confounds the very category of identity".
