Anybody who has studied Sanskrit & Tamil notices tremendous similarity. Even the sounds and letters 90% overlap. Both Kannadiga & Malayalee agree Sanskrit is the mother language but not missionary funded Tamil political class.
You can’t have it both ways. One side you push the Dravidian supremacist mindset but then claim to be part of the Northern Indus/Saraswati valley civilisation. Indian used to be contiguous land mass, one time all the way to Bali and up to Volga river - king Lalitaditya including Gandhar(Kandhar, AFghanistan.)
I don)t believe in North & South Indian rhetoric - colonial trope popular with Christian missionaries. Not only I have read Ashtaadayi but used it’s principles to build a DSL. Sanskrit was designed for compactness and ease of remembrance, does not rule it out for speaking. I live near Asharams where they speak Sanskrit even today. This Himalayan Ashram is nearly 300 years old.
You keep making false, vague and generalised self serving statements as if you lived and spoken Sanskrit for 100 years. The corpus of Sanskrit literature exposes your “zilch” mindset. So tell me few phonetic sounds which exists in Tamil but not in Sanskrit & ones which exist both in Sanskrit and Tamil ?
That will set the record straight for the audience without you trying to bamboozle us with political rhetoric.
