The Nazis taught stuff like this.
Seven to ten years later came the Death camps.
THE WRATH OF THE AWAKENED SAXON
by Rudyard Kipling
It was not part of their blood,
It came to them very late,
With long arrears to make good,
When the Saxon began to hate.
They were not easily moved,
They were icy — willing to wait
Till every count should be proved,
Ere the Saxon began to hate.
Their voices were even and low.
Their eyes were level and straight.
There was neither sign nor show
When the Saxon began to hate.
It was not preached to the crowd.
It was not taught by the state.
No man spoke it aloud
When the Saxon began to hate.
It was not suddently bred.
It will not swiftly abate.
Through the chilled years ahead,
When Time shall count from the date
That the Saxon began to hate.
Yes, but it originated with the academics.
