Final answer:
During WWI, anti-German sentiment in the U.S. led to disciplinary actions against German culture and individuals of German descent, including canceling German language programs and avoiding German goods. In contemporary Germany, laws exist to prevent hate speech and honor the memory of Holocaust victims. Additionally, the Nazi regime burned thousands of books considered 'un-German.'
Step-by-step explanation:
The question seems to be referencing the anti-German sentiment that arose during World War I in the United States, rather than Deutscher's opposition in Ray Bradbury's short story 'A Sound of Thunder.' This anti-German sentiment led to significant discrimination and cultural suppression against German Americans and German culture. Public schools ceased their German language programs, and teachers suspected of any pro-German leanings were dismissed. Cultural aspects such as music by German composers were banned, and even German breeds of dogs faced abandonment in a twisted display of patriotism.
In contrast, modern Germany has laws that prevent the spread of hate and the defamation of victims from the Holocaust era. According to Section 130 of the German criminal code, hate speech and insults against individuals based on certain backgrounds are illegal and punishable by prison. Additionally, during the Nazi regime, there was a significant incident where over 20,000 books were burned for being 'un-German,' including works by renowned authors such as Ernest Hemingway and Helen Keller.
