Work explicitly addresses racial issues, e.g. racial (in)equality, racism, or identity as key themes. Does not necessarily involve skin colour. For instance, art works dealing with physiognomy as racism and basis for discrimination may fit this tag. Also includes prejudice and discrimination against ethnic groups.
Can include non-human or fictional groups. E.g. the movie Captain Marvel, presents racism again the Skrulls, or the novel Binti, where a fictional African group of people are oppressed by other humans and by aliens. Brave New World would not qualify, though it would be tagged with “inequality” (though it doesn’t include machine vision).
