@MontereyJack,
The idea is that Lindsay Schoneweis is a source of inspiration: she isn't unique, but I'm just demonstrating the idea that if people want to make reality better, a way of doing so is to argue that nations should be ended because of any individual (the idea being that nations are negative).
Lindsay Schoneweis is an extra in Wedding Crashers (at least, that's how I came to know her, though I don't know her personally); she's the wedding guest relatively early in the film, wearing the hat.
