You are very confused if you believe that nationality equals race.
race1 (râs)
n.
A group of people united or classified together on the basis of common history, nationality, or geographic distribution: the German race.
I don't think I ever did on this thread confuse nationality with race. That's why I said things like "biased against people because of their country of origin" rather than "racist". In fact, you, with your little statements about 'Hispanic posters' seem to be the one who is conflating race and nationality!
