I'm going to tell a Chinese-American I know that she doesn't look American.
Why do you feel you have to point this out?
She's American, but looks Chinese.
It's really rude to tell someone they aren't American based just on their appearance. You should be more accepting.
I disagree with your opinion. It's okay to judge someone if it's true.
American people don't have a look. America has a diverse background from all walks of life so your statement isn't true at all. Your statement is a racist opinion.
