No, a goodwill ambassador deliberately offending her hosts would have been stupid. I suppose you believe that a man wearing the ugly tie his young child gives him for Christmas is submitting to the will of the child?
Your forceful opinion notwithstanding, perhaps you should consider that Laura also took off the scarf. Or is that part of the supposed "message" too subtle for you?
Just out of curiosity, would the host wear a Cross if Laura gave them one?.
