Separation and Segregation.
Adolf Hitler employed as part of his political policy, the establishment of a ancestry body to trace the pure Germanic racial identity in the population. Most of the teaching of this and the new medical board were based around the classification of the races formulated by the 19th century scientist Richard Dalton.
Dalton had made a study of the human races based on his cousins Charles Darwin’s Evolution theory. Believing that Anglo-Saxons where the most advanced of the human species, followed by western Europeans, while black people were nearer to our ancestor the monkey. The Jews were seen as a problematic race even to Dalton, because he was anti Christian. Hitler also was anti-Christian, but he knew how to play them for his own advantage by setting up the German Christian Union in 1930.
Many people who are racist fail to understand why we have so many different peoples in our world. Genesis 11:1-9. This might help you to understand, But despite this God says that He loves the world and his creation. John 3:16.
