I own a book called THE NAZI PERSECUTION OF THE CHURCH. in one place, it talks about how Nazi soldiers, when first conquering a city, would first gather and kill all the pastors of the city.
The Nazis were Teutonic pagans, pre-Christian.
In 1914 German soldiers initiated the famous Christmas truce because they regarded the British as Christians like themselves.
There were no such truces in WWII.
Even in those days the pastors, lawyers and doctors were the only educated people in those small towns. Killing them off probably made control easier.
