Whoopi Goldberg had a great quote, which I don't recall exactly, but the gist of it was that she does not consider herself African-American; she is American. It's the hyphen, the whatever-American that reinforces our differences and prevents America from becoming the true melting pot that it wants to be.
I thought that was awesome. Ever since then, when people ask me if I'm Chinese, or Asian, or whatever, I tell them that I'm American, born in Detroit. But my grandparents were Chinese.
