I have similar accounts from Karachi.. that too in a madressa right next to the DHA office..
It is a problem with the system.
The Quran is not taught as knowledge.. it is taught as a book and that too by disinterested social rejects and sadists.
You may have heard of Binouri town Maresah of Karachi..8000 students,all happy,well taken care of and well educated in the field they chose to study?
Same for Jamia Ashrafia of Lahore?
Then there is Raiwind Madresah in the town of Raiwind near Lahore..with students from all over the world,not just Pakistan..all well taken care of and totally free.
Zakariah Mosque Madrisah in Westridge Rawalpindi? More than 2000 students and well taken care of?
Then going global ..Here in UK we have
Shaykh Abu Yusuf Riyadh ul-Haq's Madrasa in Leicester.
Then the Madrissah in Bury Lncashire and Blackbun,Lancashire..each hosting about 400 students,under strict British Scrutiny..Never had any bad report....
and many more who are doing excellent for decades..but never mentioned in media..as the stigma against Madressahs and Learning islam has to be kept live.
......................................................
The problem is poorly managed free madrisahs...Which were created by somebody who wanted to do something good with their money..and with their one off interest,erected a building and employed a Maulvi sahab..Then moved on and forgot all about it..
Now how the poor maulvi sahab is going to take care of so many non paying students?
It does cause problems and many times behavioral issues and rage...
They will be called Fundoos if they go out collecting fund..
Honestly i have seen madrisah students starving while the locality are stuffing their faces with all sorts,and nobody takes v=care of them..
So how can you think these children will grow up to be caring and sympathetic people? They were rejected as kids,grew up rejected,criticized and hated...They learn these things and this becomes their character..
Every body is to blame not just them.
