Packs of rapists and groomers seems to be epidemic in the UK. Their common denominator is their religious and cultural background. As a psychologist, I am not surprised that this horrific phenomenon emerges among immigrants from Islamic countries. Just as any other religion and culture, Islam and Muslim culture nurture certain psychological traits that influence values and behaviour.
Abuse in Muslim culture
The Quran's description of women as inferior to and the property of men not only removes womens' basic human rights; it also influence men's view of them. As a result, Muslim cultural traditions have for centuries treated women as second class citizens, forced to marry and have sex with men against their will, and living under a constant death threat should they dishonor their family by violating the misanthropic Sharia laws.
