He thought he was untouchable, or that it was "harmless banter", whatever. He got sacked because ridiculing someone's skin colour is (guess what) the sign of a racist. Personally, I thought he should have been sacked long before for being an unfunny and generally irritating pr!ck, but hey ho... (enough people have said that about me, but then I don't have a radio audience)This reminded me of the way Danny Baker was sacked by the BBC for posting a photo of a chimpanzee.
After making a big deal about how much of a football supporter he is, and how much time he's spent at matches, it's really rather difficult for him to claim that he had absolutely no idea that posting a picture of a chimpanzee instead of a baby, might just possibly be taken as a comment over a child being mixed-race.
What next, claiming that the throwing of bananas onto the pitch is merely an expression of support for darker-skinned players?
