Please stop this drivel about India does not accept your existence. The history of partition resulting from Jinnah's demands not being met, the 24 years gap between our first nuclear tests, the option of striking installations that was turned down by M. Desai, and countless other contextual examples should be enough to dispel this notion.
However, when a certain group of people in your country adamantly refuse to believe that India is sick and tired of such hyphenation, that we want nothing other than to fix the socio-economic mess left in our country by the British since partition, then who can help you? It's akin to telling a child one's sincere feeling, whilst he puts fingers in both ears and screams what he wants to believe.
That is the real crux of it. You don't want to believe India is indifferent or focused on itself because that negates, to a large extent, the foundation of your state. You are what India is not, by definition. If India were majority muslim at partition, forget about agreeing to adopt an Islamic system of governance, the question of Pakistan would never have arisen. Being anti- something, rather than having a positive definition that stands by itself, at inception is the root of many problems.
Then, as other friends here point out, the whole economic and class-based impetus has it's role too. The feudals who wanted to retain their barbaric, medieval position of power considered it a life and death matter to preserve that system, knowing full well Nehru's socialist leanings prior to independence. They fought for 'autonomy' to maintain enslavement of tillers initially, with a provision for the right to secede if such 'autonomy' was jeopardized. Then seeing Nehru's stubbornness and arrogance, they fought to the last drop of blood in the commoner's veins to live like kings in an independent country, caring not for the immediate consequences of broken families, bloodshed and expulsion, nor for the tides that may befall the country in future.
The class struggle and socio-economic reasons are greatly underestimated in my opinion, which is why both countries don't learn their lessons and continue the same stupid mistakes with regard to where the fruits of development reach. It would be much more wise and pragmatic to focus on this issue, rather than the constant negative fixation with India and vice versa. But unfortunately, some morons on both sides continue with their insolence, blocking their ears and shaking their heads too violently to even hear a different view. We have not taken an oath to remain daft, livid and jaahil throughout our existence. The time is ripe for both of us to discard such thinking.
