(Note: the above is obviously a caricature, but current versions of theory don't change the structure, only the emphasis on "race").
No one would care about a copper-smelt site from 500 BC.; nor would they care about this one if the Indian archaeological claims were accepted (but that one also destroys centuries of Western history-making about India, and all the social-theories that depend on it).
This is all a digression from the main claims, so I'd prefer that people don't pull on this thread. For more information on how 'race' was ingested into Indology, I'd refer the interested reader to the excellent book by Adluri/Bagchi [0].
