Actor Kamal Haasan, who has announced his formal entry into politics, today said the term "Dravidian," must be expanded beyond Tamil Nadu to all southern states to get a better deal from the centre. "Dravidian is not related to Tamil Nadu alone. If we celebrate Dravidian across South India this discrimination would end. We could speak in chorus with Delhi," he said. The mega star was attacking the centre over tax collections in his column in a popular magazine, Ananda Vikatan.
