Are you familiar with the work of philosopher Lewis Gordon? Similar to your idea of misnoir is his idea of antiblack racism. In his phenomenology of racism, Gordon observes that racism requires the rejection of other people’s humanity, which is a denial of reality. Because communication is possible between the racist and the people at whom racist hatred is directed, the social reality that those people are indeed human will appear. In antiblack racism, the existence of the black person is a problem. The racist must therefore avoid and deny the social reality of the black person’s existence. In particular, the racist must avoid the embodied reality of the people who the racist hates—to make invisible the bodies that are visible. This avoidance, he says, tries to make embodied realities be without points of view and/or make points of view as being without bodies. In other words, racists dismiss black people as having a point of view, or dismiss their point of view as having no tangible embodied reality.
