Edit: I'm a bit new to the site so I'll be fumbling around trying to respond properly, but thank you all for so many great responses!
This is a bit of a touchy one for obvious reasons, but the narrator of this story is a haughty academic who thinks himself better than everyone else, and he's explicitly racist & classist against members of a culture he deems to be less "advanced" or "civilized" than his own. He insults their food, clothing, traditions, physical features, and even compares them to animals on multiple occasions.
Clearly he's a monumental jerk, and the trajectory of the narrative is set to put him in a position where he needs to be vulnerable and interact on a human level with the people he disdains, which causes him to reconsider his understanding of the world, all that -- but it's a long way off, and until I reach that payoff, how do I make it clear to the audience that his behavior isn't something I endorse?
Because it's all written from his perspective, asides are often spent justifying his positions in ways that make some kind of sense, at least on the surface, and I worry that people will take it straight and assume his perceptions are accurate to the story's world, or representative of my own feelings. Very often satires or criticisms of similar behaviors end up being completely skewed by audiences who wind up identifying with the bad conduct of flawed characters instead of recognizing the criticism. Is there anything that can be done to discourage that sort of thing from happening?
