I want to start this post saying my judgement on this issue is clouded by my current personal issues.
I was completely disgusted by the show I'm a celebrity tonight. Merv stated to Anna, "keep it up and I will chop your head of with a machete" it was completely brushed under the carpet and everyone stated he was a great guy who loves a joke. They even make further jokes about it. I am disgusted. This kind of behaviour turned into a joke on national television just glorifies the kind of people who actually say this all the time.
It is never ok, never ok to say that to another human being. In fact it is illegal!
