The construction of the concept of "race" and its connections to slavery are central themes in Butler's novel. Mark Bould and Sherryl Vint place "Kindred" as a key science fiction literary text of the 1960s and 1970s black consciousness period, noting that Butler uses the time travel trope to underscore the perpetuation of past racial discrimination into the present and, perhaps, the future of America. The lesson of Dana's trips to the past, then, is that "we cannot escape or repress our racist history but instead must confront it and thereby reduce its power to pull us back, unthinkingly, to earlier modes of consciousness and interaction."
