But the press don't support the "multicultural EUtopia" so why would they cover it up? Your logic is flawed.
Rotherham has nothing to do with the EU, Pakistan isn't part of the EU.
In his warped logic homogeneous cultures have no such problems as violent hate crime, child abuse and corruption, no doubt; he also makes the flawed link between extremist justification of crime, culture of crime and crime and culture. All of this without digging deeper into the nature of community breakdown and failed integration where it occurs, and the causes of crime. Again, 'simple answers to hard questions' is par for the course.
He might also be keen on the DM line of connecting high reporting or more robust recording of a certain types of crime with a high incidence of that crime in the community and the country at large, which again is a leap too far that ignores the actual statistics.
Hence the adopted stance of 'high quality' immigrants with better 'morals' vs 'the rest' however 'the rest' is defined. The definitions tend to follow the tabloid headlines, so I've given up trying to keep track. Though it rarely occurs to them to treat people as individuals responsible for their actions, and few ever touch on the questions of funding and running of community services, unless it's a big charity scandal or at least something that looks like one at face value.
