It was not a slip of the tongue. He was not, as he claimed, misunderstood. Sepp Blatter, who sadly is still the president of FIFA, does not make such mistakes. Despite coming out with the ramblings of an idiot, Blatter is intelligent, a former lawyer who re-invented football politics.
So when Blatter said that "one who is affected" by a racist comment during a game should realize that "this is a game" and shake hands with the player who has abused him at the final whistle there could be no misunderstanding.
It is, of course, condoning racism and in the mind of any decent, respectful human being there is no place for racism in football or in life. His defence was to say how much FIFA does for Africa. That makes what he said all right then. Like shaking hands after abusing someone who, to use Blatter's words, "does not necessarily look like you."
