Don't call me Korean!

I don't understand people these days. There are so many different Asians people in the USA. If you don't what Asian nationally I am. Don't say that Korean girl. You can't say things like that cause if the person is Chinese they will get offen. Koreans will get offend if you tell them they are Chinese. Chinese people will get offend if you called them Japanese. The correct word is Asians.
