The web and things like You Tube have made things possible that people might have wished were possible in the past when they were not.
That said, surely there are even worse injustices in the world than being a grown-up having cruel words flung at you by children. I hope some of them are getting web support too.
An injustice involves money or property. This woman was attacked on the most deeply personal terms imaginable. It was a verbal rape. At one point she opened her mouth to express astonishment at what they were saying, and her tormentor said, "I'm going to f*****' s*** in your mouth." They also said that she was so ugly, her children should commit suicide. Sadly, her son had committed suicide ten years ago. Those children totally abrogated her basic humanity. They should be hauled up for hate crimes.
