Hello ^-^, I have read the thread and I hope I'm not repeating anyone (if I do I'm sorry).
I think part of the problem of people finding fantasy more standardized is that they are more set in their ways about what they consider to be fantasy or science fiction.
Cityofmist said that fantasy literature seems required to focus more on the supernatural elements. While he or she has a point, I'm not so sure it's as simple as all that. Consider a story about an advanced alien race, which I'm sure will shout science fiction to readers from the word go. But hang on, what if said alien race believe in ghosts, wraiths, poltergeists, and what not? And as a result their culture, society, and moral beliefs are determined by their encounters with these entities?
Also consider technological advances, which again many might associate more with science fiction. I've not read The Wheel of Time, but I do recall reading on the trope page for it that guns have recently been invented. The Wheel of Time is definitely fantasy, but as Fantasy Gun Control seems to imply, readers feel guns don't belong in the genre. But why do readers object to them so? Do they feel firearms are better suited to science fiction?
I guess what I'm trying to say is that things like magic, developing technology, characters studying the mechanics behind a machine or a living organism are bare bone aspects. A story simply including any of what I've listed shouldn't indicate immediately to the reader what kind of story it is or how it will go, but it seems to anyway.
I had some more to add but maybe it's better I don't make my first post too big, sorry ><.
