What did the author mean when she stated, “we failed to sense how dangerous the nazis really were”?

The author of the comment, Dorothea Schloesser, was herself ½ Jewish in her ethnicity.  She was also an entertainer (a singer), so she would be inclined to notice how dramatic Hitler was and how outlandish the whole Nazi movement at first seemed.  But she and others in Germany were not thinking about how deadly serious this movement and its outcomes could be.  Hitler and the Nazis led Germany into devastating global conflict (World War II) and carried out horrific atrocities against the Jewish people and others (the Holocaust).

The author, like many in Germany, thought that Hitler was just saying things to gain popularity, and to get elected. They didn't realize that once he was in office, the Nazis would create anti-Semitic laws that would persecute Jews. Even though Hitler made his true feelings known about the Jewish people in his book, Mein Kampf, most people did not think that he would send Jewish people to ghettos or commit genocide.
