Excellent observations here particularly from SQ, Artex and messy. The big underlying issue here is institutionalised misogyny and one of the means of perpetuating this is dividing and othering women and girls into worthy and unworthy.
I don't want to go into too much detail for reasons that may be evident, but at the moment I have some "involvement" in a situation involving a group of 12-14 year old girls at risk of commercial sexual exploitation. Those at risk and those putting them at risk are from the same area, same socio-economic background, same ethnic and cultural group. The only difference between is sex and age and with both of those factors, power, control and influence.
It's not just being politically correct to warn against the framing of the Rochdale situation along the racial/religious/cultural lines of the perpetrators and the social class/dysfunctional family lines of the victims. That "permits" us to "other" the whole lot of them - we can tut and hiss and indulge our collective prejudices about Asians, low class people and broken families, but can afford to ignore what happened because it's over there and doesn't affect us "good people."
But, that's bullshit! Yes, it is true that race, culture, religion, class, education, family support, local traditions, accessibility, all those things are part of the mix of factors that allowed what happened in Rochdale to happen, to go on unchecked for so long. But, there's a massive risk in focussing on one or two of these factors while ignoring the main massive at the centre factor - the institutionalised misogyny. That IS the common denominator in cases like this be they in Ipswich or Inverness, Carlisle or Cardiff. And, we only have a chance of halting the damage if as a society we are prepared to accept that fact. I wish I could say with confidence that that's likely to happen soon, but I can't. That does't mean though we should give up on naming it for what it is, over and over and over.
