Most Pakistanis find it insulting if they are mistaken for Indians.
I'm talking about something deeper than knee jerk hatred. You have to look at why Pakistanis hate them. You have to look at why they cant stop thinking about them. Our preoccupation with India might be full of hatred, but it's a hatred manifested from deeply embedded jealousies.
There's a psychological rationale behind this phenomenon of secretly admiring what you, on the surface of things, despise.
