Three who described their opponents as human scum:
Josef Stalin, Donald Trump and Adolph Hitler
So far, in every case but America, calling the opposition vermin, cockroaches, enemies of the people and human scum has led to murder. America may take longer to go from words to murder than Germany or the Soviet Union, but Trump's words will eventually cause death.
This week I am leaving on a five-week trip that will include visits to some of the places where 20th century genocide was at its worst: Dachau and Flossenberg, Germany; Kiev, Ukraine; and Rwanda. Since the summer of 2017, I have been to most of the countries in which The Holocaust occurred, as well as the Yugoslav genocide. I want to see how countries recover from mass murder.
For me, The Holocaust is just as much about the 400 million Christians between the Pyrenees and the Urals who participated in or turned a blind eye to the slaughter of six million Jews. I am convinced that a Church with temporal power will eventually kill or condone killing.
Trump's Church of white Evangelical power seekers and idol worshippers will bless every outrage he commits. And when Trump's words lead to death, the false prophets like Graham and Falwell will say dead Americans are God's will.
