Outside one of Pittsburgh's many suburban malls a middle-aged woman wearing a colorful hijab held the hand of a little boy of about eight as they walked past the entrance of a department store. Three teenage boys leaned against a nearby wall. One teenager wore a printed t-shirt of a confederate flag. All three of the teenagers pointed at the woman. They laughed with a roar of contempt that exerted dominance over the sidewalk. The little boy hugged that woman's leg. He sobbed into the material of her long dress. The teenager wrapped in the confederate flag, he put his hands behind his head and leaned back against the wall in victory.
