They are a different civilization.Their worldview is different,their history is different,their heroes are different - arabs,turks and afghans,their value systems are different and their holy land is different.For them the arab culture is the highest pinnacle,what does this have to do with us?We have some genetic,linguistic and cultural affinities but thats not enough to change these fundamental differences.
We have Christians, Parsis, some Jews, North east tribals who also call themselves Indian. Many of them have different history, holy land, value systems. The idea of India is to unite all of these with India through a common idea of believing in the identity of 'Indian'. Indian Muslims are also part of the very same identity. BTW - We have many home grown heros which are common to all Indians. Eg. Abdul Kalam, Tipu Sultan, Abul Kalam Azad, Abdul Hamid
If you try to find commonality, you will see. If you dig for differences, you will see differences even within a family.
Partition was the best thing that happened,except the bloodshed.Imagine a united india with 700 million muslims.You wouldn't be able to move anything without a muslim veto.Complete paralysis.Now muslims are divided into 3 ,each one toothless.Only pakistan is a nuisance,but they cant seriously threaten us,being content just to survive,that too at the cost of slowly destroying themselves socially and economically.
You are thinking of Muslims as one monolithic bloc with a single united agenda. Reality is different. Just as Hindus are divided among regions, languages and castes. Muslims have their own divisions. A Keralite Muslim would associate more with a Keralite Hindu rather than a J&K Muslim.
By your words, you are emotionally hurting all those Muslims who are Indian. Also you are hurting our BD muslim friends. Moreover, many Pakistanis are normal people with normal lives. Our enemies are only the terrorists and their sponsors based in Pak, not the ordinary public which happen to be muslims.
Moreover with massive muslim population growth these muslims would have the right to move around,settle and enjoy economic resources of all of india.Everybody knows hindus are way better at economic production than muslims primarily the mercantile castes and communities which dominated even pre partition urban areas of punjab,peshawar and sindh.Why should hindus share their resources and ancient land with a group that fundamentally hates your way of life? its absurd.The pakistani region is an economic periphery with limited resources and power,if muslims had unrestricted access to all india it would be a nightmare.You couldnt regulate that.You would have constant migration of madrasa educated pathans and rural punjabis into our core heartland and biggest cities with more muslims dominated areas and serious problems.
Population growth is the result of illiteracy. As societies become more educated, birth rate falls. Look at BD which has a lower fertility rate today than India.
The problem of extremist thought in madrasa would not have arisen in a united India, because there would not have been a civilizational animosity.
Its more a clash of civilization than of religion.We can coexist with several other religions,but islam is too radical and different,as even europe is finding out.If the hindus and muslims couldn't reconcile after 750 years of living together it wasn't going to happen anyway.Moreover there are wounds of history as the encounter was not a peaceful one,Hindus can't forgive their medieval defeat and muslims can't get over their fall from grace from rulers to their current reduced status starting from 18th century and culminating today with mass global islamophobia,humiliation and weakness.
Till 1910s, our freedom movement had little religious color. Jinnah was already part of Congress. Remember, that Hindus and Muslims together rallied against the religion based partition of Bengal in 1899 and got it reversed in 1905.
Hindus and Muslims fought the 1857 war of independence together against the British.
With partition at one stroke you reversed 1000 years of effort and got the space to consolidate an indic empire which in time will become a great power.Muslims can never challenge us again seriously.It was brutal but necessary,safe exchange of populations should have been done,thats is the one regret.Otherwise patel and menon did a great job,we got pretty much all princely states and even nabbed most of kashmir which the pakistanis would have gotten if jinnah hadn't lost his nerve and patience and sent in the tribal lashkars.
200 million muslims is not a small number. If you think of muslims as some enemy civilization, then be prepared for further break up of India. We have to learn to co-exist peacefully. They are as much Indians as you. United we stand, divided we fall.
