Fiction should not be a refuge, where one retreats to avoid talking about political action, but a mean to dissolve propaganda, fear and impotence into a lake of acid that will prompt the reader into a life-saving jump out of deadly smooth normality.
We don’t need to write desirable futures, but to witness actual sidesteps taken by real people in our timeline out of the system. We need that because it breaks the hegemony of capitalism, patriarchy, domination, because a single example will shatter the theory and disprove it, reduce it to pieces. Because this kind of speculative fiction can make people who cannot see any alternative realize that no straightjacket nor yoke can stop them from stepping out: fiction to reassess consensus reality™ itself as a fiction—a consensual hallucination to paraphrase William Gibson about cyberspace.
