It's a question of the underlying demographics, I suspect.
Outside of my reasonably diverse university town, the rest of my county is predominantly rural and dirt poor (some of the lowest average wages in England) and overwhelmingly white. According to friends who work in child protection in the police and social services, we have a huge trafficking problem - teen girls being moved, often not very far, maybe just a neighbouring town 20 miles away, and trapped into prostitution. Here it's a white-on-white crime because that's the demographic of the area.
Let's not forget the work of American psychologist David Lisak who studies undetected campus rapists - on US campuses, 1 in 20 men will admit to behaviours which meet the legal definition of rape (ignoring "no", using body weight to hold down an unwilling woman, etc.) 30 isn't a small number for an average sized town (I think Huddersfield's population is about 150,000) - there will be far, far more rapists than that. If Lisak's figures can be generalised to the UK and a different demographic, there could be over 3000 men in that one town who've at some stage used greater physical strength to over-ride a woman's "no".
This is in no way to downplay the role played by a toxic mix of a bastardised version of Islam, and the refusal of white liberals to confront this bastardised version of Islam for fear of being seen as racist in what's going on in Yorkshire specifically. But as a general point, it's important to remember that what matters here is power structures - and the power structures may be rich white men in the BBC (Savile and his mates), white men in religious orders (the Catholic and Anglican churches), white men in sports (the team doctor for the US gymnastics team, the coaching scandal in the UK where the victims were predominantly boys), or, as in Rotherham and Huddersfield, a close community of Muslim men who, though not exactly rolling in it, were very much better off and in a stable community position compared to their victims. The common factor is men in positions of power able to form closed groups not subject to scrutiny. Any "boys club" seems to do the trick in opening the way to abuse and rape scandals.
The propensity to rape comes first, the after-the-fact justification comes second (my religion tells me these girls are "loose women, asking for it", "they're only poor trashy girls who are up for it anyway", "they're just junkies after a fix"), and is incidental to the crime.
