Are you a Labour MP? This sounds very much like 'Lessons will be learned', aka 'Shut up, this is very inconvenient'.
I'm quite prepared to believe politicians of all parties have ignored this because it was just too difficult and sensitive to try to resolve. That's not good enough, though (to put it mildly). The safety of vulnerable people should be one of our top priorities as a society. Children and teenagers need protection. It's a huge scandal that so many of them have not been protected and not been listened to. Their wellbeing and their need for justice have been ignored for other considerations, such as how many votes would be put at risk if the cultural reasons underlying this were to be challenged.
I'm a pinko heart-on-sleeve lefty liberal, and I'm strongly in favour of (controlled) immigration. I live in Inner London and the huge diversity of the community here is one of the reasons I love London. But when people come to live in the UK it is a basic requirement that they obey UK laws. Their desire to maintain the traditions of their home country doesn't trump that.
