What is called a Dravidian culture? Is it existing only in Tamil Nadu?

Dravidian is not the brain child of Karunanidhi. Even before his birth, the term Dravida was used by scholars like Dr. Caldwell. Even Rabindranath Tagore accepted the concept of Dravidian in his National Anthem. While other South Indian States are not caring about this concept for different reasons, huge population of Tamils all over the world believe the Dravidian concept. It is not because of Karuna. A single man can not create such a huge illusion in the society.Why is Karunanidhi able to play the Dravidian card? It is because, Tamils including his political opponents are the ardent lover of this concept.Even non believer of Dravidam Jayalalitha has no courage to remove the term Dravida from her Anna Dravida Munnertta Kazhakam.Believers of Dravidam concept penetrate all the castes(Except Brahmans), all religions, all South Indian Linguistics (Like M.G.R.,Vai.Ko and Vijayakanth) in Tamil Nadu. Cursing Karunanidhi, will not be a solution.It may be used to defeat him in Politics.Mind you, Tamil Nadu people are toying both Karunanidhi and Jayalalitha from 1991.They are having their own agenda..It is not real that proclaiming the anti Brahminism is one of the reasons for his defeat.He was defeated for the belief of his party's involvement in 2G scam, and co operating with Congress in killing of Eezham Tamils.Tamil Nadu people voted against Karunanidhi and not against Dravidam or Tamil culture.Also Tamils have not voted in favour of Jayalalitha. If Karunanidhi keeps his lips tight with out chanting Dravida mantra, Jaya will be thrown out from Tamil Nadu. Please readers don't visulaise this issue through the eyes of Cho.Ramasami and Subramanian Sami. Unity can be developed by love and mutual respect.Dravidian feeling exists in Tamil Nadu only.Tamils know the real history.It can not be elaborated here for want of time.Please once again think constructively , Why are these anti Brahminism and Dravidian culture, dominating the minds Tamils. If you want to estimate the solidarity among Tamils regarding their race, go through the news details about the gathering of 30000 people,with out the participation of major political parties, for paying homage to the victims of Eezham war at Marina Beach at Chennai on 26-06-2011 in the event of World war victims day. Originally, Tamil Nadu Government anticipated around 500 people. There was no untoward incident.It is the real Dravidian or Tamil culture.
