What is it about the left and hyperbole?

Ruth Marcus in the Washington Post today wrote about the terrifying and terrible prospect of Anthony Kennedy retiring from the Supreme Court, really, terrifying?  This follows proclamations that millions will die following America's abandonment of the Paris Climate Accord or the repeal of Obama Care, really?  These types of alarmist declarations will do nothing to further the causes of the left because they will not come to pass.  People will continue to live and die as they always do, and New York City is not underwater as Al Gore predicted.  How about straight forward arguments and reasoned analysis, those have become anathema to the unhinged left in America.  The elitist left who look down from on high on the their inferior brethren believes the only way to win an argument is to scare the hell out of everybody.
