non-human Reader gives so many options for degrading and insulting shit tho, I support your cause
It's not good. I have so much brain rot that I don't even have a specific character I'd like to insert, I just have so many thoughts about how to best bully a Miqo'te reader
Treating her as if she's special given the small-ish population of Miqo'te, showing her off as being one of the ~smarter, more civilized ones~ while keeping her basically like a pet. Using super derogatory language about her just needing to be bred, going into heat (I don't even think this happens, but who needs accuracy for the sake of dehumanization, right?), and being more submissive and less advanced culturally and therefore lesser. Degrading her for being associated with a more sex (patriarchal/matriarchal) based culture and playing into the worst sexist stereotypes, the Seekers having harems and the Keepers worshipping Menphina, and using that as justification for treating her like a toy because it's basically her culture anyway. If reader is a Keeper, using the justification that her lack of a properly dominant figure led her to be too difficult and in need of strong guidance. Physically using her smaller stature against her. Constantly drawing attention to her non-human traits, mocking how she can't help the way her ears fall when she's unhappy or perk up at praise, pointing out how her tail twitches and swishes and generally gives away how she's feeling. Also, manhandling reader by her tail, using it as a threat of pain to keep her compliant. And, you know, to keep her in place (or pull her down) when she's being uncooperative. Petting her ears or pulling on them depending on the situation. Making the most of her strength or agility while pointing out that it doesn't help her, that for all that her people claim to be hunters, she's less than prey.
