I suspect in the Rotherham case, it was actually easier and more palatable for the authorities - including the police - to claim that the fear of being called racist was the driving factor in their lack of response. It gave them a reason - and a response that felt more comfortable (being ‘empowered’ to act whatever the cultural background) as well as the more comfortable version of flagellation (we’re just too scared of being seen as racist).
At the same time, it allowed everyone to sweep the misogyny, and particularly the one filtered through class, under the carpet. They didn’t have to talk about the way that the police, social work, education, society at large view poor, white girls in the care system. They didn’t have to address how victimhood for women is always filtered through lenses that seek to blame women.
Instead, they got the appearance of a tough, soul searching conversation while avoiding the bits they really don’t want to talk about.
That doesn’t mean that specific cultural factors weren’t at play too. Or that they don’t matter. But it is worth considering that the misogynistic behaviour of some immigrant men stands out merely because they haven’t learned which British women it’s ok to target. Their awful, misogynistic stereotypes don’t distinguish between middle women and those too easily categories within some dreadful notion of ‘underclass’. And that makes it easier to recognise as a problem.
