Political Correctness and the MSM calls the citizens of the Indian sub continents "Asians". There are four main racial groups in India, non which are Asian. With hues (skin tones) from very light to very dark skins.
There is a sub culture of the Caucasian race, mostly in the norther parts of India. Being Caucasian does not always mean a white skinned person, far from it.
Warning..political stuff ahead: With the Islamic terrorist doing uncontrolled damage, and after the 9-11 event, the MSM began slowly referring to some Middle Easterner's (overwhelming Muslims) as Asian. Probably trying not to connect Muslims/Middle East peoples with these terrorist attacks around the world. This includes Political Correctness. Today it might take a little searching to find the word Muslim connected to the word terrorist; as Muslim Terrorist. That's a no no in the MSM and PC handbook. Other more trustworthy news outlets and reporting may use that term.
So if Middle Eastern Muslim terrorist blow up schools with children inside, than that would be called acts by a band of Asians terrorist.
