The debate about the origin of Indo-Aryan peoples is highly controversial, relating to the indigenous origin of peoples and culture, thus inflaming political agitation and sentiments.
Dravidian response
The Dravidian Movement bases much of its identity on the idea of the indigenous origin of Dravidians as opposed to transgressing Indo-Aryans. This in turn lead to further responses from Indian nationalists:
From a nationalist point of view, it is clear that the concept of an Aryan-Dravidian divide is pernicious to the unity of the Hindu state, and an important aim for Hindutva and neo-Hindu scholarship is therefor to introduce a counter-narrative to the one presented by Western academic scholarship.
Hindu nationalism
Nationalistic movements in India oppose the idea that Hinduism has partly endogenous origins. For the founders of the contemporary Hindutva movement, the Aryan migration theory presented a problem. The Hindutva-notion that the Hindu-culture originated in India was threatened by the notion that the Aryans originated outside India. Later Indian writers regarded the Aryan migration theory to be a product of colonialism, aimed to denigrate Hindus. According to them, Hindus had existed in India from times immemorial, as expressed by M.S Golwakar:
Undoubtedly ... we Hindus have been in undisputed and undisturbed possession of this land for over 8 or even 10 thousand years before the land was invaded by any foreign race.
