How did antisemitism permeate German society legally and socially?

Answer: Antisemitism became the national doctrine of Germany.

Explanation:

Antisemitism is widespread propaganda among the German people. During his imprisonment, Hitler wrote a book called Mein Kampf (My Struggle), which became the core ideology of the strongest German uncle, the National Socialist struggle. This book is full of hate and racial discrimination. Hitler needed a "scapegoat" to defeat Germany in World War I and blamed the Jews as the culprit for all of Germany's problems. Through robust and unprecedented propaganda, he sought to and succeeded in convincing German society, which began to turn to this ideology of hatred and destruction massively.
