Not all scholars agree on what fascism is. Philosopher Jason Stanley of Yale University says it is "a cult of the leader who promises national restoration in the face of humiliation brought on by supposed communists, Marxists and minorities and immigrants who are supposedly posing a threat to the character and the history of a nation." That is, fascism focuses on one person as leader, fascism says communism is bad, and fascism says that at least one group of people is bad and has caused the nation's problems. This group could be people from other countries or groups of people within the country. Under Hitler's fascist Germany, the government blamed Jews, communists, homosexuals, the disabled, Roma and other people for Germany's problems, arrested those people, and took them to camps to be killed.
