Loftwings and Demons

I'm baffled when people get offended at the idea of someone who truly enjoys SFF as a genre not necessarily wishing to engage with coffeeshop AUs or high school AU's or the like that strip a piece of speculative fiction of all its, well, speculative aspects. Like, yeah, I enjoyed the original story in large part because I enjoy that genre and the things that come with it. If someone wants to accuse me of not being *highbrow* enough to like their litfic romantic tragedy AU of the story or my tastes not *diverse* enough to enjoy their coffeeshop fluff AU, then yes, guilty as charged! But what else is to be expected here? I read SFF because I like SFF? Why is this considered strange and unreasonable?
