The farmers in the fields laughed at us when we asked them where it was and symbolically sliced their hands across their throats."Ordinary Germans knew what was intended as part of the policy of a Jew free Reich. It is not as if the leaders of the Nazi party were exactly reticent about it.

There are still people who think that treating some ethnic group as though they were disposable is somehow justifiable. And news of new "ethnic cleansing" operations seems to reach us regularly. And religious leaders continue to foment hatred of infidels, and counsel killing as a way of dealing with those who have a different faith.
When will we ever learn?
