Westmoreland's context might have been different. I'm willing to leave him on a high pedestal as a master of the insult.
You are right about Farage's claim that they never did a real job in their lives. Farage's claim was an obvious exaggeration and it was "pandering to the working class", but he was also implying that the jobs they are doing now are not real jobs, certainly not jobs he respects. When they booed him, he won. He got to them. And he did so without using fighting words.
I think you are also right about historical knights, but I am only interested in mythical or fairy tale knights, damsels and dragons. That is what motivates people when they vote, not the issues. Most people do not even know what the issues are. They don't know the dogmas of the left or the right. They are participants in a myth.
At the moment the fairy tale that seems to fit best the Clinton-Trump presidential campaign might be "Snow White and the Seven Dwarfs". Snow White is Our Future. Clinton is the Queen who follows her Mirror of public opinion and will do anything, anything, including feeding a poisoned apple to Snow White to keep her supremacy. Trump is that bungling hunter hired to kill Snow White but who later takes a courageous stand and lets her flee. The Seven Dwarfs are the rest of us. Personally, I'm looking for a third party to vote for, trying to be rational, but I don't know what tale will influence me when voting time actually arrives.
