I can agree it's a little bit racist and wrong to tell the story using that sort of slur, and honestly I kind of think likely the entire story is very racist due to being fake and made up to get a laugh at the expense of Indian people, but if it's real it seems worse to be knowingly bringing harassment down on your coworkers by intentionally antagonizing people for a laugh when you're supposed to be doing your job, I think that probably does more actual harm.
