Spring Thunder, in a very long post, essentially tries to argue that Hindutva as practised by the Congress, the Parivar and the Communists (okay, this is my interpretation) in India is nothing more than Sanatan Dharma:

The questions of nationalities as well as the languages were never solved democratically in India. The ruling classes repeatedly try to impose Hindi and oppose the struggle for national self-determination. The relationship of Brahminic Hindu nationalism with the Hindi is organic and integral, hence irrefutable. Hindi nationalism or ‘Nationalist Hindi’ encroaches in to the rights of other nationalities and suppresses them; at the same time it denigrates the people of the oppressed castes and classes belonging to the ‘Hindi belt’.
