Hhaha oh god I had to live with that
Hahah some of my friends get pissed off too...so this is what i've figured so far
Chinese- Mainland China
Chinese Taiwanese- Ethnically Chinese in Taiwan
Taiwanese Taiwanese - Ethnically Native to Taiwan and are usually a LOT darker than Chiense
in the end though they are all ethnically chinese. its like trying to argue that Iraqs and Jordinans and Syrians and Saudis are not arabs
Now in my opnion though...yeah taiwan belongs to China
but either way I can't wait for all the Pro-Roc and Pro-PRC to come run in and nuke us all to hell

amol i'm amazed someone could confuse a indian for an Iraqi. I'm iraqi and even the most dark iraqis can be confused to be seen as mexicans at first glance (tell you bother to compare the two and start to notice the differents
). Hell I'm light skineed and everyone i meet immediately thinks i'm mexican, and since i took spanish I can usually converse for a little 
But as for Indian and Pakistani...I can see that. Remember, when "India" and "Pakistan" were created huge migrations of Hindus and Muslims to each country occured so I'm not suprised at all if you could be confused.
