You have stripped all four of those quotes so wildly out of context it isn’t even funny. Maybe my memory is wildly off but:
Selkie Stories Are For Losers: You are quoting from a part where they relay a fictional story, or at least strongly implied fictional story. This is like someone telling about Homer’s The Odyssey inside of a fictional story and declaring the entire story myth.
If You Were a Dinosaur, My Love: The entire piece of a stream of concision poetry and is posing the hypothetical. It would be like saying, “I will love you until the stars die” is a piece of sci-fi.
The Ink Readers of Doi Saket: It is talking about a non-super natural event. It is like if you had a fiction story and it recounted how someone felt at church, and called that sci-fi because someone felt a spiritual feeling.
The Water That Falls On You: This slips in as the only legitimate piece of sci-fi or fantasy in the short story section, but just barely. It is much closer to magical realism. The fantasy piece is almost incidental to the actual story.
Uh yes, that is exactly the complaint. You are saying that like someone is denying it. I prefer my sci-fi and fantasy to have coherent world building. None of the above short story nominees of 2014 had anything even vaguely resembling sci-fi or fantasy world building, much less coherent sci-fi or fantasy world building. People like different things. That is okay. You lean towards literary fiction with elements of magic; I like strong world building and plot driven stories, the more grounded the better. We can like different things.
Strong world building and ground plot driven fiction is not for “little boys”. Little girls, men, women, and everyone in-between can enjoy those things too. I’m sorry you are too cool enjoy enjoy exploring coherent new worlds through fiction, but the assertion that anyone who enjoys a solid plot is must be a little boy is kind of a shit opinion on par with only boys like math.
Have you even read any of the books or short stories nominated this year? Hell, did you read the winner from last year? I hate to burst your bubble, but the winner of the Hugo last year, Ancillary Justice, was a meticulous piece of world building utterly devoid literary appeal. It is solidly in the “wizards and dragons and robots” category. What it did show is that you can open the genre without ignoring the elements that make it unique. Ann Lecke, coming from a clearly unique point of view that sci-fi needs more of, built a world of “wizards and dragons and robots” that thoroughly destroyed tokenism and did one of the best jobs at building a coherent human but alien culture that I have ever seen.
The opening of sci-fi and greater inclusion doesn’t mean that sci-fi has to become magical realism and a subgenere of literary fiction. It means that women and gay folks get to jump on space ships and go explore the universe too.
I can’t speak for everything on that was nominated, but you clearly have not read most of it. If you think that Goodnight Stars, a story written by a queer socialist lady, is a sexist diatribe for “little boys”, you have been navel gazing too much.
