There is no rivalry in MotoGP more bitter than that between Valentino Rossi and Casey Stoner, more bitter even than the one between Wayne Rainey and Kevin Schwantz. It has been a constant element in their relationship since Stoner won his first MotoGP title in 2007 (ironically, Stoner named Rossi as one of his heroes on the t-shirt he wore to celebrate that championship), though hardly a surprise, as the two men are polar opposites in almost every respect, except for their prodigious talent. The rivalry has intensified over the years, stoked by a series of incidents (nicely outlined by the peerless Italian website GPOne.com recently), including the booing of Stoner by Rossi fans at Donington in 2008, the epic battle at Laguna Seca in 2008, and the war of words between the two in 2010, ahead of Rossi's move to Ducati.
The rivalry does not just polarize the two riders, it also polarizes their fans. The comments section of almost any news story featuring the two men is riddled with posts by people blinded by fanaticism, with logic and calm consideration nowhere to be found. This polarization leaves the media with a dilemma: on the one hand, events concerning the two, and verbal exchanges between them need to be treated as newsworthy, and due consideration given to covering them as such. On the other hand, the media operate in the certain knowledge that covering the dispute is sure to sell more newspapers and magazines, generate more traffic to a website, and grab more viewers for a TV show. Reporting on these stories leaves journalists open to charges of sensationalism, but not reporting on them means they can be accused of not doing their jobs.
