[I]n matters of race, silence and evasion have historically ruled literary discourse. […] The situation is aggravated by the tremor that breaks into discourse on race. It is further complicated by the fact that ignoring race is understood to be a graceful, even generous, liberal gesture.
Toni Morrison, Playing in the dark: whiteness and the literary imagination. 1992. Harvard University: Cambridge. p. 14.
