Sport delivers the message that hope can defeat hatred
Symbolism is everywhere in sport: triumph over adversity, David versus Goliath. It is also a conduit for a rather less savoury kind of imagery – an extreme example being the 1936 Berlin Olympics. Given its universality, it can be no surprise that sport reflects most things about our society, the good and the evil.
However, even by these standards, it has been a remarkable week. First, West Bromwich Albion striker Nicolas Anelka was charged by the Football Association after celebrating his first goal against West Ham United with the 'quenelle' – a gesture he says is purely an anarchic one, but most people believe carries anti-Semitic overtones.
Then Stan Collymore, the former striker turned radio pundit, received such a tirade of racial abuse via Twitter after suggesting Luis Suarez dived to win a penalty that he was forced to spend his birthday on TV news and chat shows challenging the social networking site to do something about it.
And finally, Beth Tweddle – one of the nicest, most hard-working and unobtrusive athletes you will ever meet – was subjected to such a flood of cruel insults, again via Twitter, that even hardened hacks at Sky Sports News, who arranged the studio Q&A, confessed to being "absolutely shocked and sickened".
All individual cases, but all sharing a common theme: the recognition that sport has the power to carry a message widely, immediately and with such a resonance that it cannot go unnoticed.
Sport might also occasionally be hijacked by a person, or a movement, for the wrong end, but it has been used as a global platform to make society-shifting points for the better, too.
The most famous is the Black Power salute at the 1968 Olympics in Mexico City. What if the raised, black-gloved fists of Tommie Smith and John Carlos had been ignored?
Another was Nicky Winmar, the Australian Rules footballer, who responded to racial taunts in 1993 by lifting his St Kilda jersey, pointing to his indigenous brown skin and yelling at the Collingwood, Melbourne crowd: "I'm black – and I'm proud to be black."
What if photographer Wayne Ludbey had dismissed that gesture as attention-seeking, rather than a powerful social statement that made the front page of the Sunday Age newspaper?
Sport is about opinions; it is one of its core strengths. People care about it deeply. Another image that was impossible to ignore last week was of Sjinkie Knegt, the Dutch speed skater, raising his two middle fingers to the back of rival Viktor Ahn, who was celebrating his winning leg in Russia's team relay gold medal at the European Championships.
Knegt was disqualified for flipping the double bird, but at least it showed he cared about defeat. Sport would be so much poorer if we tried to constrain passion.
If crimes are committed, or rules broken, there will be consequences. Just as some people will shout stupid things from the stands, others will fire off idiotic Twitter posts.
But so long as boredom remains a stranger to sport, there will be opinions from across the spectrum. We cannot have freedom of expression without hearing, or seeing, things we find offensive. It is the reaction that says more about our society anyway.
Judging by the public response last week, one which reflects the moral decency of the majority, sport's message of hope rather than hate is winning through. That in itself is symbolic.
