I'm friend with some of those. True Kashmiris are Anti Indians but equal # are Pro Indians too. It's because of Kashmir issue, I found PDF & got hooked to it.
2 years back, I wasn't even aware of It & some of them used to Abuse India on my face. However, now things have changed, they don't dare to say such thing in front of me.
Like a normal citizen of India, Kashmiris also enjoy all the rights which we enjoy, in fact they have more privileges then us. Hence, they have no right for referendum. All the problems they face today are created by them only. The sooner they realise, better for them.
If Pakistan gets Kashmir, it secures Water for them, as the rivers which runs in Pakistan originates from Kashmir. Sab Paani ki ladiye hai...
PS: there are equal # of Kashmiris who hate Pakistanis to core, like they hate India.
