Some things are much more important than football though.
Agreed. However, I don't think it is up to an individual player to decide he doesn't like something and walk off. I am amazed at many of the things that football crowds say and amazed that they are allowed to do so. This is just one of their many repugnant themes. But will players now be allowed to decide as individuals on a game-by-game basis whether to walk off if supporters say things they don't like? If this were to spread we could see players walking off for lots of reasons, which would obviously be unworkable. Would it not be better for the police, football associations or clubs to be taking the decisions in an organized manner rather than individual players on an ad-hoc basis?
For my money, I'd much rather leave the decision in the hands of the black player being abused at the time, not the organisations that clearly know very little about racism when deciding on it after the fact. Blatter/Fifa/Uefa only prove this point time and again when real punishments are needed for incidents like the Serbia-England youth game recently when they do next to fuck all about it.
