Something i recommend people who really want to understand this have a look into, is the issues that come with the Mirpuri pakistanis. I would put money that the vast majority of the men involved in the grooming gangs are from that region. I know this from Pakistani friends who fucking detest them, partly because most of the bad stereotypes of Pakistanis is because of that exact crowd and they get lumped in with them. We had serious issues with them and their kids being complete bastards towards my daughter when she was in primary school in Levenshulme, but so did everyone who wasn't exactly like them, including British born pakistanis, and the black kids got it the worst (they were significantly in the majority at her school and i know for a fact the problems there haven't stopped). Really grim ultra religious zealots.
Saying all of this as this nuance is really fucking important and i hope it starts to get discussed more. Pakistan's a big place, it's the lot from Mirpur who are almost entirely causing all of this shit.
