Listen, America is a very big place, and there are lots of people living in America. That much I'm sure you're aware of. But doesn't that make you stop and think, for just a second?
Think about it. Russia, China, and America. They are the three biggest "countries" in the world where people say to people "I'm Russian", "I'm Chinese", "I'm American". Broadly speaking, I come from Europe, but I'm Irish when anybody asks.
IMO when national identity includes a HUGE amount of people, things get skewered. That's why partisan politics is an easy route to take, because then you can have two clearly defined Americas, and if you don't like one way, campaign against it from the other side.
But here is something I have come to believe (that's right, I used the "B" word). People are people, and it takes all sorts to make up a town, to make up a state (American terminology), to make up a country, to make up a world.
So, to be an UnAmerican American is probably to fit neatly into being a certain type of American. I know it mightn't seem it, but trust me on this one. Not because I'm wise or any bullshit like that, but because, though it may not seem like it on the ground, none of that shit really matters.
