Well many years back when the Gujarat riots had happened and we knew the full extent of what had happened, the Pakistani community decided to raise money for the thousands in refugee camps. We were with registered charities and decided to raise some money from Indian mosques alongside Pakistani ones, Bengali ones etc. Among the Indian mosques the reception was the least enthusiastic, even though their families had been directly impacted by the riots. In the end enough was enough and their collective committee that had influence/control over many mosques told us that we were not welcome as Pakistanis bring Jihad with them wherever they go. That day literally shattered my illusions of that we were tight, brothers etc. I had a big go at one my friends whose idea it was to go to them.
As the years have gone by I haven't let that incident to influence how I interact with them and they have my respect but it was a hurtful reality to wake up to.
