I'm Chinese American and I agree. I too find it easier to identify as Chinese-American / Asian-American.
I live in and was born and raised in NYC around large Asian communities, so I feel like I'm fortunate to grow up learning about my parent's culture and where they're from but at the same time I'm a child of a completely different culture. I often find myself feeling torn between the two. I'm not Chinese, my birth certificate proves I'm American, however I often don't feel like I can represent myself as either.
My fiance is White American and the glances and stares we get when we're in more homogeneous parts of the country are pretty telling.
