American was a unique people (including genetics), language and culture for the majority of the existence of the country of the united states of america. Its only in the last 50 years there have been noticeable non white, non black populations with a few exceptions like the Japanese on the west coast. Generally, the country has been 85-90% white, 10-15% black and 1% "other", so thats how most people in the world still think about it.
Also the idea of becoming another nationality just doesn't make sense to the majority of the world. You'll never meet a Japanese person who believes they can become Indian, etc
