Are you claiming that ‘linguistic analysis’ by non Indians/Hindus at the university of Texas supersedes knowledge that was orally transmitted for aeons before linguistics as a term was even coined?
Plenty of Indians/Hindus conduct the same sort of linguistic analysis, beginning with a guy called Panini who lived around 800 BC. In any case, the nuance and depth of the arguments in the University of Texas article far supercedes the a priori (and apparently religiously nationalist) statements you are making here.
Historical linguistics is an evidence-based field of study that many Indian scholars also actively participate in, wherein they also analyze non Indian languages.
