Making the subtext text, not that it was always sub, maybe shub niggurath, here's Lovecraft with the racism, or racism and Lovecraft existing cosily side by side making life difficult for coloured folk in post-war US. A coloured family becomes entangled with the sinister doings of an occult society, but that's merely an added complication to the dangers and inconveniences of the racism they experience in their daily lives. Ironically, the latter gives them the fortitude and instincts to deal with the former, though they'd prefer not to have to deal with either.
