Sonnen doesn't want any fighting to happen out the cage, hes got more manners and class than most fighters
Insulting a whole nation (to name just one thing) is not what I'd class as having manners and class.
One might say it was a bit of comedy and all part of the act but the man isn't a comedian, he is a professional athlete.
I do agree that Silva should have risen above it - he did say that he'd shake his hand after the fight.
