Yeah, I don’t know about this. The Handmaid’s Tale has provided us powerful iconography to communicate tyrannical, white male power. Atwood acknowledged the racism of the system head on, multiple times.
What more could she have done? Are you really saying we shouldn’t use this very effective iconography because the book focused on white women, which again - was exactly the point: women of color were erased because of tyrannical, white male policies. Seems to me that the story actually pushes the conversation on race forward.
