Very nicely put, Bhai. No I don't differ from you. The Indian subcontinent/South Asia is not one country, it never was throughout history. It's more similar to European Union though and there are far too many similarities to ignore. The subcontinent is a distinct culture from the rest of the world. Just because we focus on similarities does not mean we should reunite (I'm not a fan of the Berlin Wall parallels).
We Indians don't agree with the two nation theory based on religion alone but I understand the Pakistani perspective very well. Your Quaid e Azam wanted to separate from Congress-ruled India, and it is proper as 100% of Pakistanis agree with that view.
As I mentioned before we are a single cultural grouping, there are a lot of similarities, that no one is ignoring, nor should be ignored, but in this partition, we are "one" narrative everything else gets ignored.
Europe lives peacefully with itself now, they have lot more similarities then we do, many royal families have the same bloodlines to this day, British royal family had German name till world war 1 after which it was changed.
Arabs are a far more a singular nation then South Asians can ever be, but live peacefully in as different countries, without this hurt about an imagined past.
I honestly want someone to disprove me, or show me what the problem is, I just don't see it, it all looks manufactured, basic on a false idea of single historical nationhood. but I have to say you are among the rare Indians who see history as it was. But having said that, Punjabi and the Bengali are the only ones who know what partition is because they are the ones who were partitioned. And no one else.
The paramount recognition of identity is that it is self identifiable,
religious belief is always a part of that identification, how much a part can depend on how different groups choose to identify themselves. It is a fact that Muslims, Hindus, Sikhs and Christians have distinct identities, so why has it become a problem if Muslims identify themselves as a single group, it is not a problem for others.
Jews after thousands of years of living as different ethnicities, white, black, and brown but can identify as a single nation, Sikhism has been recognised by the UN as an ethnic marker so if a white or black person becomes a Sikh they can identify to a singular Sikh identity.
Christian Europe went to Jerusalem making a claim to holy land they had never set foot on before. They came from different countries with different ethnicities but identified as a Christian nation. Religious marker is a nation if that is how you choose to define yourself because identity is self-defined, that is exactly what the Hindutva project is, a Hindu nation. The two-nation theory was just that, protection of Muslim rights as grouping, I don't see whats to agree or disagree. The two-nation theory has been oversimplified because no one challenged the established interpretation.
I honestly would have loved to see a European union type arrangement in South Asia, I think it would have been acceptable to all sides, but it is becoming an increasingly unlikely future, with the Hindutva agenda at play right now. But let's see.
Please do offer a different interpretation of what I said if there is one, maybe I am not seeing it. Thank you.
