Those are poor laborers, laborers - no matter who they are and where they're located - always have to keep their heads down and tolerate any sort of treatment from anybody to eke out a living, especially when they're the smaller migrant population who can be kicked out at the drop of a hat.
If you think the situation would be the same once the demographic is literally flipped upside down, and that too with people who are there with Government packages & armed/trained for self defense - not as poor laborers surviving on Kashmiris' mercy - then you're badly mistaken.
People used to talk the same sort of smack in Gujarat (I don't think I have to explain that Gujaratis are well known for being disinclined to violence), especially in the days of Congress Governments which used to protect & utilize Muslim Gangsters; all it took was one burnt train and 50 Hindu bodies to change things overnight.
PS: You went on a long spiel about UP/Bihar Muslims selling their daughters and sending maulvis. I'm surprised I even have to clarify this to you, but I'm obviously talking only about Hindus. Why the hell would I want to send more Muslims to an area that's already a hellhole due to concentrated Muslim population. Didn't know I had to spell that out.
Bhai Lancer Ji, Do not take the subject to the tangent.
The solution of J&K does not lie in demographic changes. Pakistani Jihadist did that in valley, POK and GB. No use.
What was old time valley? Even Kashmiri pundits used to behave as if they are from some other world. Even they used to claim of dual citizenship and say they are not Indians, supported, aided and advised the Jamaati Seikh abdullah, cornered all government jobs thereby bringing a sense of discrimination / alienation amongst Muslims, were inimical towards Jammuwala Dogras and Sikhs and specially Maharaja. They played their Nehru card much more than desired specially in higher echelons of bureaucracy in Valley and Delhi. In due course of time there was violent blowback. However, I am not justifying that.
Everyone is stark naked in that Kashmiri Hamam.
What is required is bringing in political balance in J&K. Political "gundagardi" of valley Muslims due to their majority population needs to be balanced politically. that can only be done by inclusion of population of POK and GB. On other side of Tangdhar and Pir Panjal, there are hardly any Kashmiri.
