Sorry dude! I was not aware that an Iranian will get similarly ticked off by being called an Indian as a Pakistani does.
Navid, by the way, can be a very common name among Indian Muslims.
And we are not insecure, as you wrongly think. We Pakistanis easily and openly talk about our failures and shortcomings. What ticks us off is that people who have problems of their own take more interest in us than to focus on solving their own problem.
Some Iranian pick up misconception, spread by the Indian media, about general Pakistanis. I have a good number of very close Iranian friends and have found that generally we become friends very easily. So chill bro!
