The Black Hebrews are a tiny meaningless cult who have been yelling crazy things on street corners for decades. All they want is press attention so everyone just ignores them. If those children had any common sense, or any sort of adult leadership, they would have walked right past them and ignored them. Instead they decided to get into a confrontation.
Luckily there was a NA veteran there to diffuse tensions, until one little dirtbag kid decided that an elderly NA man was a better target for his racial animus than a group of Black Hebrews, and decided to initiate a confrontation.
Scott Adams is an idiot.
