The acts carried out by the parents are far more shameful than anything the girl did. I'd like to know the wider British Muslims' attitude towards it because if a large portion support what the parents did then it's a real problem in terms of future integration, the girl was basically abused and ultimately killed for wanting to adopt her country of births' culture.
Well there is some level of support as it isn’t the only case and the whole point was to preserve their families “honour” within that community. It is common enough within Pakistan and the authorities there are quite lenient, even complicit or willing to turn away when it happens.
Of course the sibling fortunately did come forwards, after some time, unfortunately didn’t try to actually stop it or raise the alarm/call 999 when it happened though. Likewise another family friends had letters etc... but didn’t reveal them until after the sibling came forwards. This sort of abuse of daughters is certainly something that people in that community can and will attempt to keep quiet about albeit if they’ve actually gone as far as to kill then it is much harder to cover up.
General abuse, forced marriage of cousins etc... that can go on without consequence. Ditto to say FGM in other communities such as Somalian etc...
