Tamilians are ignorant lot. Many sanskrit words in Tamil language they think it is pure Tamil words!!! U list down some Hindu Gods with local names and say they are Jain which even original Jains of today have'nt even heard of...Ur Nadar Jains even today's Jains will not accept as their people.
eg: Varada is sanskrit, Raja is sanskrit, Chala (Venkatachala)Pathi (Lord in sanskrit, Venkatachalapati) are both sanskrit words. Kapali is also sanskrit... Shanmugha is sanskrit which means six-headed. (Shal-six, mugha-face) Meenakshi is also sanskrit. Meena(zodiac sign;Pisces, fish) Akshi(Eyes).. Which is the so called pure Dravida and Tamil in these??? May be Perumal yes... it is not sanskrit. even Ambal is sanskrit(Amba=mother). People who have no sense of sanskrit end up in wrong conclusions about Indian hisstory.it is natural
