In 'The duty to miscegenate', I harness John Stuart Mill's 19th century theory of social freedom to explain and to dismantle contemporary racialised and gendered injustice. In the first chapter—Social stigmatisation: 'a social tyranny'—I argue that persons racialised-and-gendered-as-black-women were, in the past, unjustly stigmatised by legal penalties against 'miscegenation' and are still, today, unjustly stigmatised by white male avoidance of cross-racial marriage and companionship. In the second chapter—Encounters that count: 'a foundation for solid friendship'—I argue that we can dismantle this (...) stigmatisation, by engaging in regular and frequent cross-racial commensality with persons racialised-and-gendered-as-black-women. In the third chapter—White right: 'a right to avoid'—I argue that, although we have a right to avoid commensal encounters with others, we do not have a right to avoid persons we racialise as black. On the contrary, we have a duty to encounter them, on terms of equality and intimacy. (shrink)
