Thanks for your comments! In a thread a while back I commented on American lawsuit culture and I agree that it is not a good first step.
The more exposure introversion gets the better. This exposure should be through awareness efforts, like books, meet up groups, etc.
The way of America though (a lot of it) is to train its citizens to be consumers. The best consumer is an outgoing, "lively", extroverted individual. So we'd have to tackle the very fabric of American culture, which in my opinion, is worth it.
We have to make small steps, but loud ones.
We have to work our way into television (show more introverted leading roles that depict success, etc), and all other forms of media.
One of the real problems is that as soon as extroverts perceive introverts to be separate from them, it is going to be really easy for them to discriminate against introverts, this is why I posted those two job listings.
They are subtle indications but VERY REAL.
