But they have shown an openness to learning. Instead of responding, like some commenters have, by getting mad at their potentially ignorant sentence, it’s a far better approach to, like some other commenters have, educate them about the fact that the very nature of privilege means that as part of the privileged class you get to live life being oblivious about the class distinctions.
That is indeed the privilege of the privileged. And the burden of the unprivileged is that they do not have the luxury to live their lives while being oblivious to their lack of privilege.

It's entirely fair to point out that different castes would see and experience casteism very differently...but sheesh, it's tiresome to see a bunch of (probably white) keyboard warriors show up and argue with in Indian American about what it's like to be Indian in America.
I'm an Indian-American as well. Don't make assumptions.
In any case, there are some deeply problematic aspects to Indian culture, including that of my own community, and criticism of them is warranted, no matter the demographics of the critic.
