So what? That doesn’t mean that it’s “insulting” or “offensive” for the cafeteria at Oberlin to serve beef kheema (or beef whatever). If it’s “insulting” or “offensive,” then every Indian restaurant in my area that offers beef options is “insulting” or “offensive” and the Oberlin-ites need to go protest it, too.
It WOULD be wrong if they were to label a dish as vegetarian when it was beef – but that wouldn’t be specific to Hindus / Indians - it would be because, well, people wish to avoid certain foods for a variety of reasons, whether it’s religious, health, or social consciousness and it would be sloppy and careless not to be accurate about what is in there. But that’s not a “microaggression.”
BTW are you going to answer Nrdsb’s question about why you claimed that I thought it would be funny-ha-ha to sneak beef into a vegetarian’s diet?
