What’s the hypothesized reason why American universities are evidently discriminating against OBC persons? To my knowledge most Americans know little to nothing about caste, few of us can reliably tell caste from name, and even if we could we wouldn’t care.
The subtext is that other people of Indian descent are doing the discrimination. So far as I know, nobody asserts that non-Indians are aware of caste, or could possibly identify caste from names.
