Dude you have some serious comprehension issues or you are mentally unstable . Kashmiri people are fighting a war from last 6-7 decades, no one needs to brain wash them but they see their parents, relatives , and young people been killed in fake encounters , women been raped . The only one Brain washed is here is you but I think you are not because for that you need a brain which i doubt you have .
As for your last argument , Idiot Kashmir was a Muslim Majority state which should merge with Pakistan, as per Partition rules , you took a lot of states based on this very rule but when it comes to Kashmir you are showing hypocrisy ? remind me how India took Hyderabad ?
Kashmiri people will keep fighting this war until they get what they deserve , and generation after Generation will keep struggling , neither the bloodshed in valley will stop nor India will stop bleeding .
