Let's be clear about what is being minimised here:
The Rotherham Grooming (child rape & torture) Gangs scandal involved an estimated 1,400 children between 1997 and 2013. The rape victims were mostly vulnerable white girls aged between 10-14 at the start of the abuse. The child gang rapists were predominantly British-Pakistani men. This is one town in England. Just one town.
Official reports, including those by Prof Alexis Jay and Baroness Casey, found systemic failures, cover-ups, and a total dereliction of duty by the police and social workers. Very young, vulnerable girls who were the victims of gang rape, were disbelieved, or ignored, or casually dismissed as 'child prostitutes' making poor life choices by the people whose job was to protect them.
It was so very shocking, to so many people, because we expected paedophile rapists to need to hide their evil behaviour from all their family, colleagues and friends. Here we saw so many examples of brothers, cousins & uncles, people working at the same taxi firm or fast food outlet, all forming groups to gang rape children.
Something was, and is, very wrong.
