"This is not something I confess easily. I have long been shamed out of owning my introversion by the extroverts who dominate American culture. Extroversion has long been considered healthier than introversion, and introverts often try to push against our natural tendencies in order to fit in, to seem normal so people will stop scolding us. Extroverts are unintentional bullies, demanding that everyone join their party or be considered queer, sad or stunted."
The 'we're oppressed' thing just comes off as so bitter to me. Maybe I feel this way because I'm a lot more sociable than I used to be and have seen this issue from both sides.
I've noticed introverts who have become more outgoing and those who haven't have very different takes on the issue. Those who are still introverted tend to be a little more bitter and into the victim thing, and say introversion is a core personality trait.
Those who worked on becoming more outgoing will say their desire to socialize is more mutable than they once thought it was, and that a lot of their past so-called introversion was just shyness and not liking being around people because they weren't good at or comfortable with it. They still seek out and enjoy their alone time, but on the whole they say they're glad they got better with people.
* It's possible the ones who changed weren't hardcore or 'real' enough introverts.
* You could also start nitpicking the way I used the term, and start debating what 'introvert' really means, something most discussions on this topic devolve into before long I've found.
