I've always been under the impression that most imageboard shitposters are in real life quite meek. The sort of person who didn't get enough love as a kid and grew into a socially demented, depressed pervert who does their best to keep their failure to thrive under wraps through submissive behavior. The sort of meek, quiet nerd who goes online to act out their fantasies of being a cool narcisistic psychopathic to compensate.
