The ironic thing about parent comment is that for as much as it bashes the Hugos for being part of the “old guard,” they’ve actually been very good about surfacing and including queer- and minority- centric stories and works by authors with identities that have historically been excluded from the discussion. Arkady Martine won Best Novel in 2020 and 2022 with two entries in a series featuring a lesbian main character, with imperialism’s effects on those who are colonized as a major driver of the plot. Between 2016 and 2018 N.K. Jemisin swept the Best Novel award for successive entries of her Broken Earth trilogy, which revolved around themes of racism, environmental cataclysm, and slavery. The year before that the winner of Best Novel was Cixin Liu’s Three Body Problem which was the first time a work originally published in Chinese won, and then the year before that Ann Leckie’s Ancillary Justice won, which created a massive uproar amongst the more reactionary types in SF fandom for positing a civilization where the only recognized gender was female (this is super unfair to the book, through, because there’s so much more going on thematically beyond that one small world-building choice!).
In fact, the way that the Hugo voting has swung noticeably towards exploring issues of imperialism, colonialism, and identity is what prompted the Sad Puppies campaign that OP mentions. What he doesn’t mention is that the Hugo voters overwhelmingly rejected that campaign, and the organization made changes to prevent any future attempts. That part of what makes what happened with the 2023 Hugos so surprising and appalling – it’s completely out of character with the recent history of the awards and the organization to meekly knuckle under and self-censor for fear of angering Chinese authorities, when it’s been so bold in standing up to outside influences so recently. I expect that steps will be taken to prevent a repeat occurrence.
