Most north Indians are also polite. My sister married a North Indian Punjabi dude. Half Sikh (mother side) Half Hindu (father side). I have been to their house etc and even though they follow a culture, even though they made me dance with the Eunuchs the day after marriage
, they are actually nice people.
As for the army, well, there are opinions on both sides, and India does what it feels is in its best interests. The best way to come to a solution is for Pakistan to arrest all the extremist forces, and then talk to India. If that had happened instead of wars in the past, I am sure by now both countries would have reached a credible compromise. But, we cant turn back the clock. I feel from Pakistan's side a lot of bad decisions were made, especially between 1965 and 2000.
As for religion, I am an Atheist. I dont really care about any religion. My dad is Christian, my mom Hindu. So my home is secular and non religious. As well as liberal.
