- Toleration
- Freedom of expression
These are not exactly as popular in Europe, and I do think that the lack of a true "Americanist" ethnic identity is what is responsible for both of these truly positive attributes. Hell, even immigration restrictionists are generally careful to insure that they're perceived as only being against illegal immigration, though the extent to which it is true is debatable (and every once in a while there's a bona fide racist like Tom Tancredo who pops into the mix).
Anyway, I feel like I'm constantly talking about what I feel we can improve about America, so I always enjoy the opportunity to talk about something that is genuinely good about our country.
