Dead wrong on Hindutva, here are my arguments against it :-
1) Not every person in a civilisation is same, especially Indian civilisation was always a caste based civilisation, why should a shudra feel proud of ancient India when all he got was humiliation and inequality for more than 5,000 years? Not only this, the genetic structure is fundamentally different between castes with Brahmins having a high amount of ANI and untouchables being a proxy for Dravidians; others being in between.
2) Your ideology Indicism is very recent and is akin to claiming likes of Al-Ma'arri, Al-Hallaj as part of Islamic civilisation which I see as nothing but historical revisionism - the only Savarkar was good at. More on this
3) Can I consider Asaram's cult a part of the Indic civilisation and thus superior to any other philosophy/religion/culture? You see, what you're propagating is cultural chauvinism which refuses to look into merit of ideas but stick to only chauvistic attitude about nativism.
