even as somebody who follows a more nationalist mentality and approach, I fundamentally disagree with you for the sole reason that you as an indian and non-Muslim wouldnt understand the notion of brotherhood which transcends borders. I wouldnt expect you to.
However, it is true that culture, language and other ''artifacts'' cannot be denied or buried. Today, we have warm relations with Bengali brothers --and it works better this way that we are sovereign countries with friendly ties (economic, militarily, and so forth)
But, what is the source of Indian oneness? Is it not the glue of Hinduism itself that people, who do not even intermarry with each other, have come under one flag? Of course, it is also a British legacy, but no one can deny that Hinduism has also glued the otherwise different people. But, then Indians will come out with their arguement of secular crap.
Look at all the modern nations of western hemisphere. They are also bonded together because of religion, like Christian Catholics and Protestants. Is this not the reason that Norh Ireland desires to remain a part of UK, and is not willing to unite with their same race and same language Catholics in the independent Irish Republic?
Why to deny the fact that both religion and language as well as history create a sense of nationhood or oneness, although, there is no unversal rule which will precede which one. Bangladesh was not created out of frustration because Pakistan was a MUSLIM country. In reality, Bangali Muslims had created Pakistan or initiated the process of creating it. Bangladesh was created because of a conflict of interest, economic and political, between the two wings of the country separaterd by another big country. A physical proximity would have resulted in the continuous unity.
The present identity crisis stems from the AL's continuous effort to change the character of our identity as a Muslim liberal nation and to make us a secular nation. To us AL policy means no Islam and no religion. This is what we are not willing to accept. However, our identity as a nation state where every religion people are free to pursue their faith remains as it was during Pakistan time.
Pakistan's original goal was similar to this and was set forward by its founding father Muhammad Ali Jinnah. Only, the next generation Pakistanis changed this concept and accepted a radical Islam. However, BD will remain a liberal Muslim country. BD has no conflict with Islamic identity, but it is also not necessary for BD to become a part again of a Muslim country that is 1500 km away, only to prove ourselves as Muslims.
