Fake outrage peaks over nonsense

Some people are pretending to be offended by Trudeau's illustration of the old saying, "bringing someone's head on a platter". They are pretending that they think he's making fun of poor Nick Berg, who I am most sure did not ask to be a phony martyr for right wing racist arguments justifying the war in Iraq.
Twenty bucks says anyone who is offended would probably consider himself a patriotic, Christian sort and therefore would be familiar with the story that is associated with the expression. Or do we only read the parts where Paul admonishes women to know their place and the Ten Commandments now?
