I think once the Holocaust/WW2 ended

The Nazis held a book burning event in 1933, where they publicly burned books deemed "un-German" or against Nazi ideology. These burnings aimed to erase ideas and authors considered contrary to Nazi beliefs.

Most of the public book burnings took place in May 1933 in Berlin and all major German cities including university cities - where many Nazi students(!) were particularly enthusiastic about it.

You may be thinking that Hitler & the Nazis burned books. Yes some books that the Nazis did not like were burned, however this was done for publicity. Actually book burnings were not a major feature of Nazi German life. The Germans valued books & education in general, and would have burned anti-Nazi books & books written by Jews.

Faber blames society and individuals for allowing book burnings to happen. He believes that people's fear and apathy towards knowledge and critical thinking are ultimately responsible for the destruction of books and ideas.
