Punching someone over steak and chips has nothing to do with political correctness. You're going to have to think harder than just relying on the tried-and-busted PC canard again.
People punch people all the time for all kinds of reasons, not all of them have a week long investigation. But are you trying to say the BBC is not highly concerned with it's own political correctness? He almost got sacked over a number plate that may or may not have been selected on purpose but come on, it's a fucking number plate. Every week seemingly he's in the news for saying something slightly dodgy or giving someone a funny look yet the beeb behave everytime as if he's the worst person...in the world.
