Both Du Beke and Russell Brand made offensive comments, which were subsequently reported in the newspapers and led to a subsequent crescendo of complaints to the BBC. The difference is the responses that both complaints have received.
At the time of the Brand outburst, the campaign was led by the Daily Mail and it resulted in Brand's resignaton and the suspension of his middle-aged side-kick idiot savant Jonathan Ross. Elements of the media were outraged that an orchestrated campaign by the Mail had led to this outcome.
Du Beke's comments, which unlike Brand's were never broadcast, have been picked up by the anti-fascist group Hope Not Hate and the BBC has seen complaints quadruple. They argue that his use of the word 'paki' was more offensive than Carol Thatcher's use of the word 'golliwog' and demand tough action against the dancer, who has apologised for his outburst. Thatcher, you will remember also made her comments in private, off-camera and they were never broadcast. She didn't apologise and was sacked.
The BBC is, however, sticking by Du Beke.
Aside from who has been the most offensive - an impossibly complicated argument - the real question is why has the BBC acted differently in every episode given that it is supposed to have procedures in place to deal with this. Also, while there was a kickback against Brand's treatment at the hands of the press, there is noticeably less so against Du Beke who was exposed in the News of the World.
While I regard the Daily Mail in utter contempt, I can understand that any of their journalists who do have souls might be feeling a little confused by the rest of the media's ability to be inconsistent as that of the BBC.
Ultimately Du Beke, Brand and Thatcher all leave me cold so I'd never employed any of them in the first place.
