I think its more a cultural issue than religious. I've grown up around the Muslim community. The people doing this aren't strict Muslims. They might not even go to Mosque. Some drink alcohol etc.
A lot of people doing this use religion as an ice breaker to meet like minded people. These people tend not to be religious and don't listen to the Imam's or their parents.
We don't fully have integration of the communities. We're living side by side each other. Unless you have Muslim friends from school and you visit each others houses otherwise people dont tend to visit each others areas socially. So we have one community is trying to enforce a strict religious mind set, while they see white people going out at weekends getting drunk etc. Meanwhile many in the Muslim community end up going to gym's and playing sports.
There are people in the Muslim community who want to join in the activities of the white community. Some even go to nightclubs, drink, and socialise with women (something frowned upon in their own community). Most women dont want to be involved in that kind of situation because they know its mainly about one thing. So sadly this is why certain people go out trying to find vulnerable women and girls. I've no doubt money changes hands between the men, and its become that lucrative and depraved that we end up in the situations that are now being reported on. There is this sub gangster culture that as particularly thrived in some communities that is difficult for the older generations to control. The gangster element is what as corrupted the systems setup to protect these girls in the care homes. There is a lot of manipulation that goes on of the adults that are supposed to be protecting the kids. I think the cover-up's are more about the adults being embarrassed that they have unwittingly been manipulated and become involved in the facilitation of abuse.
