Meh, we have the dance club crowd and the sports fan crowd. I’m part of neither (and sports fans share too many similarities to fanatic religious militants for my tastes) but I understand them.

Introverts are underrepresented in society, but I think this is due to extroverts dominating politics and industrial upper management so polities tend to favor extroverted behaviors.

Also while extroverts enjoy social behavior, they do not enjoy toxic social interaction, as is typical in the workplace. No one wants to be micromanaged and bullied and humiliated by their bosses. I think this figures largely in the telecommuting conflict going on right now.
