Much as i actually do like Clarkson, i think it's kind of being looked at from the wrong perspective. He's not been suspended for saying something stupid this time. He's been suspended for (allegedley) punching a co-worker. That's gross misconduct in any job you have apart from boxing and MMA! If i were the reciptient of the punch and then the guy got reinstated because he's popular, i'd be mortified.
I'll be gutted if he does get fired, i geniuenly like how he says it how he sees it. But i won't be surprised or feel sorry for him, due to the nature of the incident. However if it transpires that this is all handbags or bullshit, then he should be back without question
