This is a well-known story but it's worth repeating for the important lessons and grim warnings it continues to hold for the very survival of the Sanatana civilisation, culture, ethos, and way of life. It is the story of Bishop Robert Caldwell "Appa", a decisive stepping stone in what came to be known as the “Dravidian Campaign.”
Bishop Robert Caldwell floated a groundless theory of linguistic differences, as well as an equally spurious racial theory to support his linguistic theory. The Christian missionary apparatus almost immediately lapped up Caldwell’s formulations to their advantage. A whole new history was created. Hot air balloons like “the Shaiva Siddhanta was not a part of Sanatana Dharma but had its roots in Christianity” were floated. Srimad Ramayana was turned on his head with Ravana as its hero.
In the late 1960s and early '870s, the toxic Ravana Kaaviyam, a Tamil poem, was officially patronised and widely disseminated by the then DMK Government, and thanks to the popularity of this twisted work, societal tensions escalated. These brazen anti-Hindu antics were given a booster dose by the predominance of the unofficial political-religious dogma of the era: secularism. Like poison is mixed with faeces, both these forces contributed to all-round wreckage of the original Tamil culture, which at its core is essentially a pristine expression of spirituality. The other facet of this wreckage was the intensification of the rupture of the Tamil society, whose manifestation is best observed in Tamil cinema.
