It sounds like you agree with me. Ethnic conflicts are a natural consequence of immigration, and they die out over time. They used to be more pronounced in the past, and American history is littered with it.

You don’t even seem to think caste conflicts are a pronounced or big deal, so I’m not sure what we were even arguing about.

And yeah, caste is supposed to not matter for Christians, muslims or sikhs - but in practice that matters where you are.
