"I have no idea what to say in rational response to such an extreme (and I might add, insulting to at least half the nation) take on the election success of the president elect."

Really, utilitas?   Trump didn't get the support of over half the nation.  He finished second in the popular vote, and over 100 million voters didn't vote out of either indifference or Republican voter suppression.  Considering that the president-elect is a lying, misogynist, racist ignoramus who is including neo-Nazis in his inner circle, perhaps those voters who voted for him deserve to be insulted.
