In brief, AIADMK was always seen as a positive force whereas DMK is seen more as a party always brood over negativity, hate politics, anti-God, anti-Hindu, anti-Hindi, anti-Brahmin rhetoric.
The genes of hate politics against Brahmins, Hindi and Sanskrit language, North Indians as Aryan race, calling all Tamil people except Tamil Brahmins to be Dravidian has gone so deep in the state.
Satire: Explaining and exposing the fake Aryan Dravidian theory created by the opportunists.
The confusion of Dravidian or Tamil is deep rooted and the confusion was intelligently being created by EV Ramasamy Naicker and the sister political force of EVR ideology, the DMK.
The way EVR abused Tamil language, culture and literature including Tiruvalluvar has to be seen as the part of such greater design.
Shakuni caused destruction of the Kaurava clan but on the contrary Periyar helped his followers to capture power but did nothing to eliminate caste system within his manufactured race called Dravidian.
All the recent genetic and anthropological studies have shown that no two separate race of population exist in India and the theory of Aryan versus Dravidian is nothing but a myth.
