As I keep telling my countrymen; whether Muslims in India are elevated to some messianic status or nailed to the cross, nothing gives us the right to mistreat our Hindus for doing so is against all norms of civility and fairness, it is against the explicit commandments of Our Father - Muhammad Ali Jinnah and is completely at odds with our religion.
So far as Pakistani Hindus not being allowed to join the Army till the 2000s or the Intelligence community is concerned - I don't know; maybe
@Icarus or
@Xeric would be able to confirm that ! As I understand, the only thing that happened post 2000s was a concentrated effort to recruit more ethnic and religious minorities in the Armies and not that ethnic or religious minorities were barred from being recruited pre-2000s.
Additionally the Army's own press-release (dated March 23, 2014) mentioned Ashok Kumar as a Shaheed so I dunno where the author got that from. The press-release can be accessed here:
