I'm familiar with the broader social context of gender and race in the US. So when I see, for example, a coworker who consistently argues that female candidates are too aggressive, I can gently prod the discussion towards focusing on his technical feedback and deferring to the other interviewers for soft skills. With caste discrimination, I have absolutely no idea what the equivalent would be, and it'd surely be inappropriate to corner one of my Indian coworkers in the break room and ask her to teach me all the common Dalit stereotypes.
