you should know that no Tambrahmin (who have access to the power in the centre e.g Nirmala Sitharaman, Jai Shanker) will accept a Tamil sudra as their equal.
Tamils have contributed immensely to India, historically (Chola /Pallavas expansion into South East Asia) , culturally/religiously - Hindu revivalism, economically and scientifically etc. But they are yet to be given official recognition (unlike in Singapore) but their rights been tramped upon and taken away, resources exploited, NEET, Hindi forced down their unwilling throats.
Refer to the recent remark by Amit Shah on NIA amendment Bill

Pakka Hindu Tamil or not - an average Indian's perception of Tamil - periyarist, anti National , separatist, linguistic chauvinist, dark skinned Dravidian sudra speak a funny and an asura (Ravan's descendants)
For a Tamil is concern, the Indian notion of nationalism (Hindutvaism) or Hindu identity is a deluded superstitious conviction that they have an overriding religious/cultural solidarity with the rest of Indians. Strangers, most of whom they have never met, will never meet and have nothing in common - racially or culturally e.g religion and language. Better late than never, time for Tamils like the ISRO chairman to wake up before Hindis / brahmin give them the used condoms treatment.
You should remember before the British there was no India and Hinduism hence the concept of India and Hindu is an artificial British creation
