Look at the IIT Bombay photo, in the background is the colonial era copy of Lady Britannia - "Bharat Mata". The fact article is hosted on Open Magazine, I was already a bit suspect. So the full context missing from headline is - "Under Hindu Nationalism".
What the article misses is what some of these accounts post. SanskritSparrow channels his followers on stories to some kooky post which claims to have decoded Indus Valley Script as Sanskrit. Learned persons better be careful about the intent here, the rider that is riding the "ancient" horse into the present is as much trying to invade intellectual spaces, as the actual Rishis were trying with the lands. Besides, the appeal is only among upper caste Hindus. What else is a Dalit going to do with Sanskrit? No literature is written for them in Sanskrit. They're not even allowed learning it, it is an exclusive domain of Brahmins. What will Dalits get from reading Vedas and finding out how they are termed as devils and filed under a degraded caste pyramid? It's an article borne out of very rosy lens. A Dalit Ambedkarite writer should research the accounts mentioned and tell us what the subsurface vibe looks like here, is it the same old wine in new glass?
