Generally, human nature is such that, after some years and experience, humans try to raise above national & parochial narrative and show more interest in finding & propagating truth.
But I guess - Pakistanis are exceptions. The more experience they have, the more narrative they want to believe (most desperately). Maybe, the environment is such that - any questions asked will probably have consequences. Hence, everyone will parrot the national narrative louder and louder.
PS: This is not an ad homieum attack on your person (or) on any other pakistani. Please don't take as one.
