Man your idea are all in a twirl. Who told you that those people are still there? Gee, use some sense. Pakistan and India both have similar issue about Kashmir. It stands to reason that their approach would be similar too. Why would it not? The only difference is that Kashmiris on Pakistan's side have not stood up in revolt or anything like that because they feel better accommodated. Kashmiris in IOK are a bit different I guess. But the more you repeat stuff about Punjabis buying up Kashmir, the more you open yourself to ridicule.
I shall disregard irrelevant parts of your post and come straight to point of concern. It takes two hands to clap. Our situation vis-a-vis one another is not strictly a Hindu OR a Muslim problem.
The stuff about guilt and all is just a distraction. You are reading your interpretation of history into it. It is not necessarily correct or relevant. Mughal policies were practically secular in nature - had to be for them to continue their rule. Their problems with Sikh Gurus were because of perceived aspirations and interference, starting from beginning of Jahangir's rule when his son revolted and solicited Sikh Guru's help. It was NOT a religious quarrel, at least not so from Mughal perspective.
Your analysis is off the chart. Too self-serving as you conveniently forget Aurangzeb. There is no self introspection and the causes are sought outside rather than inside. And I am sorry but I am immediately reminded of Taqiyya, holy deception, Qur’an 5:32 — Winds Of Jihad By SheikYerMami
