just to be clear, are you disputing that Suarez said "I don't talk to negroes" or are you saying that there is a context in which "I don't talk to negroes" is acceptable?
Obviously, why would he say that with many black team mates/friends/family and a country with a large black population.
As for the whole negro/negrito being used in an offensive manor whenever it was said is another matter, the fact Evra changed multiple times the exact word Suarez called him and how many times makes me suspicious.
As for the 'well Suarez changed his version', yes largely because he wasn't thinking about having to recall it during the game (could you remember word for word what was said with a mate last night?) and he wasn't given the video to explain his version of events, Evra was. They wanted to make an example of someone with no proof and they did it.
The media also helped
