It's ironic though that the sole reason 1,400 children in Rotherham were sexaully abused for years was that social wokers and others were afraid to admit that there was a large pedophile ring who were all Asian/Muslim. Apparently anything is better than being labelled a racist.
Having said that I do think it is likely that there has historically been abusers in positions of power.
Butler-Sloss resigned because "her late brother, Sir Michael Havers, was Attorney General at the time of the alleged abuses in the 1980s.
Sir Michael, father of the actor Nigel Havers, reportedly tried to stop Tory MP Geoffrey Dickens from using parliamentary privilege to name diplomat Sir Peter Hayman as a paedophile. He was accused of a "whitewash" after failing to prosecute Sir Peter."
