Are you joking. A grown man sat on another (deaf) man's chest in the middle of the street, swiping at his neck and face with a big blade and gouging his eyes out. Did you not see the video? The victim is still in hospital with life-changing injuries.
A young girl ran at a grown man and swiped at him from behind. No injuries are mentioned in the article so I assume if there were any, they were minor. Her ideology is evil and wrong but probably the result of the fact that she has been denied any education because of her ill health.
The vicious, brutal man who did real damage is not British and a recent arrival, the young girl who didn't hurt anyone very much is British and has been neglected by social services, the education system, mental health services.
The riot does not make sense in any context but the anger does. Why is it so hard for some people to understand why and how context matters?
