As an initial matter, all racist comments are uncalled for, in any context. In this case, though, that holds especially true. America has long been a melting pot for people of all races to come to pursue their dreams. Thus, an Indian American champion is the perfect symbol of that history and should be embraced.
There is no place whatsoever for racist comments in today's contemporary society. No one needs to be racist towards anyone, regardless of who or what causes the remarks. Racism is born out of fear. We have an open society where everyone is free to express their opinions, but racism is way too hurtful.
