Nope, I wasn’t trying that - and it’s all the east coast ones that confuse me.
There is more to our country than Disney and Vegas.
Should in the sense of it’s a good thing to know rather than “one must”… Because this country is so large, there is a lot of regionalism. If you plucked a random person each from New England, the deep south, the mid-west and the west coast and compared them, you’d find they sound very different in both accent and word choice, different levels of education, they probably have different amounts/types of religion, have different cultural beliefs/activities/histories, very different diets, different laws and political views, and perhaps different career options.
“Expected” to know? Not much, really. All I ask is a bit of humility.
I say that because it’s taken for granted in much of the world that Americans are ignoramuses (ignorami?) who don’t know anything about the rest of the world.
And sadly, there are an awful lot of Americans who know little or nothing of the world.
Europeans, on the other hand, tend to think they know a LOT about the U.S.A. It just so happens that a huge amount of what they “know” is wrong.
