Today I removed the following paragraph: 
 :Some people consider it offensive to label an Asian person with a specific nationality without certainty. For example, labeling someone who looks South Asian as an "Indian" may be offensive to Pakistani Americans and other South Asians who do not consider themselves to be of Indian origin. Likewise, calling an East Asian "Chinese" without knowing his specific national origin can be offensive to Japanese Americans, Korean Americans, and other East Asians who consider themselves ethnically and culturally separate from the Chinese. If one is using racial or ethnic terms, it is more politically correct to use "South Asian," "Southeast Asian," "East Asian," or simply "Asian." 
 This etiquette lesson is, at best, arguably encyclopedic.
