Speaking of an "typical american" is as stupid as speaking of an "typical european", even worse I believe, though most of them have at least one language in common compared to europe with its dozens of utterly different languages.
But nonetheless, regarding my own humble experience, I found most americans beeing really kind, straight, honest and generous people, and despite these qualities, they can be quite (irritating) modestly too. I believe even behind the "fuck off, leave me alone"-attitude, some of them have, you still may find a big, bumping heart in the right place. They live, struggle and suffer as we all do, well, probably in a more intense way. A lot of them have managed to create incredible beautiful and touching things like art, literature, music and other amazing or insane stuff while they have been living in the worst nightmare you can't nor you like to imagine at all. You won't find this special kind of strength and creativity very often outside america. Especially their music can tell you a lot about them; if you're open minded and dig deeper.
It's true their culture is quite dominating, from an european point of view, but this is because they're often just freaking good in what they do, and the "language" they speak is one everyone can understand. Since the U.S., as well as Canada, were founded by people who came or fled from every thinkable place of this planet, americans are the sum of all these origins. Squared. So, from a different view, we're all americans. If you want to see one, just look into a mirror. If you hate them, you probably just hate yourself.
Regarding U.S. residents, I hope, wish and pray they get their act together again, that they get over all this sad shit they suffer from and rise like a phoenix. Come on. Nobody can smile like you do, show it to us again. I'm missing it.
