Am I Croatian American?

I was born in America and I am white. I do not call myself a Croatian American; I am third generation for God's sake! Living in Los Angeles and having numerous black friends, I do know that they prefer to call themselves black. I think this is an interesting topic however, because I always sort of stumble when I am speaking with a new friend or at the office...to use "black" or "African American?"

Interesting stuff here.
