The Nazi's demonized the Jews, and though many scoffed, they persisted. Many of the scoffers went to concentration camps. Denial can have horrific consequences then and even NOW. Take it personal, as they were then, they are like now. They have already tried a crystal nacht here, cities burned, hate magnified, rebellion against law. Fear and terror used as a political tool, manipulating usable fools. How shocked they are when they get sentenced, as i said, usable fools.
Yes, history can and does repeat itself. All thats needed for the wicked to prevail is for good men to stand idly by and do nothing.
