Always bothers me when people yell "Racism" when they mean religious prejudice, or national prejudice. "Anti-semitic" does not mean "anti-Jewish" but that's how it's used, "anti-American" should be "anti-US" and so on.

US folks have plenty of ignorance about their own country, too, compatriots of mine. There are those who ask if they need passports to visit New Mexico, if you can use "American Money" in Alaska, or if Idaho really exists at all.

The answers to the above are: yes, if you're from some furrin country; of course, in fact, leave all of it and they'll take care of it for you; and nobody knows, not even those who live here.
