Hell yeah. It's always the extroverts that act like they're the default and introverts just need to be coaxed out of their shells. I think that it comes from the common misunderstanding that being introverted is the same thing as being socially anxious. I think they probably go hand in hand, in that a socially anxious person is possibly introverted as a defense mechanism but it's not the same. Being introverted just means that you have a limited social battery that takes longer to change.
