Here's the thing that you need to understand about the Grooming Gangs scandal.
Britain is very divided on class lines; watch one of their "realitainment" shows on youtube (Benefits Street or Can't pay? We'll take it away! Are prime examples) if you want to get a good idea, or see how people who live on benefits are portrayed in their tabloids.
They are far harsher on their poverty-stricken than Canada. There's a serious resentment to those people. They are portrayed as living off stealing and drug-dealing, clad in designer clothes that they stole and behaving in the most reprehensible manner.
The Grooming Gangs scandal mostly took place in filthy areas, and the most telling quote (paraphrased) would be "they were slags anyway" from an official.
Take the murdered girl who broke the entire cover-up open for example, had been on Jeremy Kyle in a show about out-of-control kids. She was 13 at the time, the family was just how you'd expect considering it was Jeremy Kyle.
It turned out that she'd been the victim of a grooming gang since age 11, and that led her to being Britain's first white honour-killings.
To get a Canadian perspective, imagine how it would be if a grooming gang scandal was unearthed where the victims all lived in the public housing around Jane and Finch or in the worst parts of Scarborough. People would be furious, but not "rebellion-level furious."
UK isn't on the way to becoming a failed state, the sun never sets on it and the ravens haven't flown. They're just starting to undo decades of damage, as we will be shortly.
The real men are here, and they're fine but you can't expect them to get violent at peril to their own families unless things truly get out of control.
The problem is that the real men live nowhere near the slums where this shit occurs and they aren't particularly threatened by it.
