Whether its fair to say Hindi is our national language?

Hindi is a national language for hindians. Tamil is the national language for Tamils. Kannada is the national language for Kannadigas. As simple as that. India is not one nation. It is a land of multi nations. Not one culture, but multi cultures. Not one language, but multi languages. We need integration of Nationalities and not just national intergration. If someone does not respect another language, then there is no national integration. If you impose Hindi on other language state, then it is anarchy, autocracy and not democracy. This will pave way for disintegaration.
