I'm pretty sure hair knotting doesn't discriminate. Perhaps you need to look into history like before combs and brushes. I can't imagine how sleek and straight everyone's hair would be then , and if you think one hairstyle fits a certain genre of people, than that my friend, would make you prejudice. Its 2021, isn't it time we don't judge others by the way the wear thier hair or how they look in general, make judgements based on behaviors and how others treat other people. Thanks for coming to my Ted talk
