I would assume it is much more insulting to be called a "Paki" for an Indian. And pretty much a compliment for a Paki to be called an "Indian."
India is growing economy which has given science many advancements and is the home of many intellectuals. in science and math.
Pakistan umm.. is pretty much a failed country.
Lol pakistan is one corrupt ass motherfucker. India is too, but at least not so much at a national level.
