Well if Tamil literature is so rich as you claimed, I am still not convinced why it has only couple of Gnanapeetha awards againt it. As far as the population is concerned please count the no. of Tamil speaking people in other parts of the world like Malaysia, Srilanka and many South East asian countries.BBC has included Arabic and Urdu languages too Why? Its just the number game man. Tamil may be the oldest language after Sanskrit.Kannada is the third oldest language which is independent of Tamil though it has minor influence from Sanskrit.Tomorrow I will send you the link which proves Kannada is independent of Tamil.This article was written by one of your Tamil scholors from US university.I mentioned Kannada has been always pro-hindu because till today there are no books in Kannada which are against Hinduism where as Tamil has so many books written againt Hinduism.Hope you got my point this time.Every state in India is Secular so please mind that. Lastly I am not against Tamil or Tamilnadu.I just wanted to make some clearification about your claim on Tamil.
