until you understand that this is a part of Pakistani culture. Pakistan is one giant Rotherham, except boys are the victims since females are kept from the public square.
You couldn't re-institute this cultural practice among Euros - likely because European psychology has changed over past few thousand years.
It just turns one tragedy into two.
(i.e. imprison the personality types that you don't want to reproduce)
So it's doubtful that "telling" British Pakistanis to change their culture, or assimilate, will be effective.
