In an interview back in 2008, Tepper announced her faith in eugenics as a means of dealing with persons:
"who look human but who are uncontrollable or who habitually hurt other people will no longer be defined as human,” she said in a 2008 interview with Strange Horizons .
Walled cities will be built in the wastelands and all nonhuman persons will be sterilized and sent to live there, together, raising their own food. There will be no traffic in, no traffic out, except for studies that may be done which might lead to a ‘cure.’ There will be no chat about this sequestration being ‘inhumane,’ because the persons so confined are not human by definition.
(Whether she is unaware that forced sterilization has been used routinely against low-income women of color well into the 1970s, or whether she simply doesn’t care, isn’t clear.) Tepper’s ideal society is a terrifying dystopia in and of itself, and once you know that about her, it’s easy to see those politics reflected in everything she writes".
