I've never had any trouble discussing this with European and American colleagues or owning up to my own privilege.

But I can see how many Indians would find it awkward to talk about, especially if they think that the caste system is on it's way out because things are better than they used to be. Some might feel that discussing it with non-Indians puts India in a bad light.

To which I say, it's not me who's painting India in a bad light, it's the people who are discriminating on the basis of caste in 2020. People who say "oh, I'm only against reservation and those who benefit from it" and treat such people terribly. And we can only get rid of this disease by shining a light on it.
