A completely wrong take. This was found/reported in the one place in the south of India where they would like to believe that they are different. Certainly unconnected to "Hindu nationalist orthodoxy", whatever that means. Entirely possible that this claim is an overreach but if it was, it would be for the opposite reasons stated by you.
you could be right. I don’t know.

I asked perplexity ai exactly what the hindu nationalists believe about the aryans. This was the reply.
///////////////
many Hindu nationalists believe that Aryans originated in India and spread westward, rather than migrating into India from elsewhere. This view, known as the “Out of India” theory or “Indigenous Aryans” theory, is popular among Hindu right-wing groups and some Indian scholars.
The “Out of India” theory emerged in the 1980s and posits that India is the homeland of the Aryans, who composed the Vedas, built the Indus Valley cities, and then migrated out to Iran and Europe2. This belief aligns with Hindu nationalist ideology, which emphasizes the indigenous origins of Indian civilization and rejects the idea of Aryan migration or invasion from outside1.
Hindu nationalists often find the concept of Aryan migration unpalatable for several reasons:
It challenges the idea that Aryans or Vedic culture were the singular source of Indian civilization1.
It puts Aryans on the same footing as later Muslim conquerors of India.
It conflicts with the emphasis on racial purity in some Hindu nationalist ideologies.
However, it’s important to note that current genetic, linguistic, and archaeological evidence generally supports the theory of Aryan migration into India, rather than out of it. Despite this, some Hindu nationalist groups continue to promote the “Out of India” theory and campaign to remove mentions of Aryan migration from textbooks
