I didn't quite understand. Is this related to what the article says: " The discovery of a civilization of people who lived before the Vedic people upended the story of India. Given that it undermines their claims of indigeneity, proponents of Hindutva — the most mainstream strain of Hindu nationalism — balk at the theory of a pre-Vedic civilization, even as evidence for it accumulates across disciplines, including archaeology, genetics, and linguistics. "
Is Sanskrit and Hindutva and PIE related?
