Have you taken any literature or maybe other media classes at the 200 level?
Sometimes people say really weird things and I wonder if they just don't know any better. Maybe they're a teenager.
But like "fact from fiction" is irrelevant here. No one's saying Dracula is non-fiction, but you can still read it and take meaning from the text. Furthermore, it's not just a story about a guy who bites people. The read on how women are expected to behave is pretty obvious, for example.
You don't have to care about the subtext of "kill all the goblins and take their stuff", but saying there is no subtext or "no one cares" is absurd and self-centered.
