Hannah said the Nazis were not committing a crime against the Jews, but a crime against humanity. Although she said that because Jews are human beings, her meaning may include Nazi leaders, executives, bystanders, and the Jewish upper class. The executives and bystanders do not have anti-Semitic thoughts, but these people can be accused of crimes against humanity.
I haven't gotten into it yet, but guessing. The Nazi leaders were at the center of evil, and a series of extremely dark crimes were ordered by them, anti-Semitism. For the middle and bottom people, as performers and bystanders, they give up the most important characteristic of being a human being: thinking. So their act of committing crimes is anti-Semitic, but their refusal to think is anti-human.
By extension, a person who gives up thinking and relies on others, without simple judgment ability, is anti-human. I'm thinking about contemporary again.
