That's silly. Obviously all cultures have their own issues, and I'd say it's actually rather patronizing to pretend that non-Western cultures don't have their own dynamics of bias and discrimination.

Having said that, as a cultural Westerner, I'd be very loathe to speak much on the topic of the Indian caste system, as while it's clearly a real thing, and I believe those Indians in America who say it is, I'm certain I lack enough context and background to talk about it without it ending up being an exercise in projecting my own culture's dynamics onto theirs. It's the kind of conversation I think I probably need to do far more listening that talking in.
