Reveals the alt-right's project to claim science fiction and--by extension--the future Fascists such as Richard Spencer interpret science fiction films and literature as saying only white men have the imagination required to invent a high-tech future. Other white nationalists envision racist utopias filled with Aryan supermen and all-white space colonies. Speculative Whiteness traces these ideas through the entangled histories of science fiction culture and white supremacist politics, showing that debates about representation in science fiction films and literature are struggles over who has the right to imagine and inhabit the future. Although fascists insist that tomorrow belongs to them, they have always been and will continue to be contested by antifascist fans willing to fight for the future.
