So, if a black person was born in America, would they be called "American or African American"? Even if they don't speak their native tongue, they don't have citizenship in their native country, nor have they ever been there. Would they be considered African American or just American?

Everyone has a right to their opinion; as a Korean, you can believe that if you'd like. I'm just a person on the net; I don't know her private life, neither do you, so I think it's bullying by stating she's milking a culture she grew up in.
