This article aims to explore how Jamaican-born writer Claudia Rankine displays the ways in which, as a black woman and a first-generation migrant settled in the United States, she ‘regularly has to negotiate conscious and unconscious dismissal, erasure, disrespect, and abuse’ (Rankine [2020] Just Us: An American Conversation, New York: Penguin, p. 23). Just Us: An American Conversation is a genre-defying work that includes poems, essays, photography, visual art, posts from social media, and academic and journalistic sources that tackle the discursive constructions of whiteness in cultural and political life in the United States. In this volume, the private and the public merge through conversations with white strangers and friends at the airport and the train station, in the classroom, in the backyard, in the street and in social distancing interactions via Zoom. Berlant ([2011] Cruel Optimism, Durham: Duke UP.) writes about public spheres as ‘affect worlds’, where emotions precede rational or deliberative thought, attaching strangers to each other and defining the terms of the state-civil society relation. I also use Sara Ahmed’s idea of ‘encounter’ (2000, 2012), defined as a meeting with others that surprises and involves conflict, because it shifts the boundaries of the familiar or assumed knowledge. In this sense, Rankine creatively looks for traces of racialized and gendered experiences in encounters that involve bodies or texts, including the devastating effects of Covid-19 on marginalized black communities. The volume completes a vital trilogy that includes the hybrid book-length poems Don’t Let Me Be Lonely (2004) and Citizen (2014). This lyrical series conform what I call ‘a black poetics of affect’, shaped by intimate public encounters with racism and sexism that disrupt the fantasy of a post-racial society. Rankine’s sustained reflections on ‘the affective dimensions of Black life’ (Palmer [2017] ‘“What Feels More Than Feeling?”: Theorizing the Unthinkability of Black Affect’, Critical Ethnic Studies 3:2, pp. 31–56.) provide new and situated insights on affect theories and feminist studies.
