I, one of Asian person, feel why this was so controversial?

I think that big round eyes are attractive and beautiful, but narrow eyes make nothing harm with anybody. Although these girls were treated as like some kind of racist, I don't care about what stinkies had teased us.
I think that a lot of western people don't know is that almost all of Asian people is scentless. 100% of Mongolia and Korea, 95 to 98% of Chinese and 80% and more of Japanese people is scentless. A lot of Asian people ain't no need to care about thier airmpits and crouch.
Thus, I think that Asian people who having narrow eyes are nothing wrong with anything, but stinky people isn't in this case.
