This is just an observation. I am a staunch believer in the Hindu way of life - non-violence, industrious and socially productive work and at least minimal spiritual direction.
Would you say that Shivaji Maharaj should not have liberated Madhya Pradesh, Karnataka and parts of Tamil Nadu from erstwhile cruel Moghul kings? Did not Shivaji Maharaj himself send so many Maharashtrians to other parts of the country to ensure that these very divisions would not happen? Was not Shivaji Maharaj a perfect politician and strategist? Is not Rajnikant an example of exactly this population? Would Shivaji Maharaj tolerate this divisive system? Was Lord Ram not from UP? Lord Krishna? Both Ram and Krishna travelled the entire Indian subcontinent without opposition. That means that even at that time, with all the various kingdoms, big and small, India had a strong bond, much like the EU today. So, when we have a federally structured constitution with proper separation of State and Union portfolios, and a better democracy than the US, why should this politics of division make sense to anyone? Would you not agree that had this kind of divisive politics happened back then, human supporters of Ram and Krishna would have faced problems? Are we greater than the two Avatars, to state that India is not a whole? Would you chuck out Kabir? Or Radha? Or Sudama? Or would you want Birbal to not come to Maharashtra?
