"India" was never there before, either. Punjab, Sindh, Khyber Pakhtunkhwa, Balochistan, Kashmir, Gilgit-Baltistan, and the Muslims of northern India have a rich history just like any state of India. But tell yourself whatever you want, we really don't care. It makes no difference to us whether Pakistan is 70 years old or 40 years old. The point is that it does exist and its people wanted to form the country and live together.
It was not founded on "hate", but by a desire for self-rule. And consequently, that the views of its citizens be would not be drowned out by the religious majority. I wonder if you would feel the same way if the populations of the subcontinent were reversed and the minority Hindus formed a union of Hindu-majority provinces. Somehow, I don't think that you would accuse that country of being formed out of "hate".
No one in Pakistan supports this, and they never will. Try actually visiting Pakistan sometime. Pakistanis would sooner die than let this happen. Not to mention that the country has nuclear weapons now.
Again, seek psychiatric assistance. It's time to come back to the real world.
