The American identity sucks if you're white skinned, because of the whole genocide thing, also it's too new, too cosmopolitan, and not real to most other people.
I dunno American Identity sometimes seems more real outside the US.
There's the fact that we constantly tell americans who don't speak a word of german or french that they are neither, they are american to us, no matter where their great-great-grandparents were from.
And then there is the time when an aquaintance of mine one day seemed very happy and I asked him why he was so chipper. He said he'd figured out that over here, he wasn't "african american", he was just seen as "the american" and that had never happened at home. Yes he clearly was recognized as black, but it never once came up as a qualifier on his identity.
