I am an American, oh no, I am white, and I am hated for my parents' hatred.
I am an American, oh no I am Asian, black, a mud with full white brothers and sisters, maybe full Asian or even black, or oh no, a Muslim who lives with Islamic culture.
I am an American and I have to protect my country against other countries. Oh no, my brothers and sisters are of those others countries.
I am an American, but I hate all others who do not look like me. I am an American, but I hate you because you don't think like me. I am an American, so are you, we are all Americans.
