You obviously have no idea what you’re talking about.
Do you realize that the Muslims of UP, Bihar, Madhya Pradesh, Delhi, etc. all voted in favor of the creation of Pakistan, but (rightfully) didn’t get separate Pakistani enclaves built into their home states? Pakistan could only be carved out of those districts where a majority of the population supported Partition. As it stands, there isn’t a single tehsil in the Kashmir Valley where the majority doesn’t support independence.
And before you even bring it up, even before they migrated, even in major Pandit population centers like the Habbakadal and Rainawari neighborhoods in Srinagar (we’re not talking about tehsils or even towns now, but individual neighborhoods), Hindus only comprised 30-40% of the population.
The “Muslims of Kashmir” live in approximately 25% of the total land of the Indian state of J&K. By all means, keep the remaining 75% for all of the India supporters.
