It's a shame that you call Luis a racist... The way he talked "negro de mierda" he was using a very common expression in spanish "...de mierda" and we use it every time for many things. It's rude and not very good manner but we use it the same way you use the word "fuck" or the expression "fucking something"... for exemple "fucking bitch" to call a woman that she is very bad and nasty but you don't mean she is a prostitute. I'm not defending the ways of Luis, (he is not very nice but the way) but the way you treated these subjet it's very sensacionalist and very far from reality, !Ingleses de mierda! -) (this is a joke)
