In real life people like that can do real harm, and I think a valid criticism of the film would be that it pulls the punch on what that ignorance can really do in real life and focuses on the humanity of people who do and believe awful things Not an awful theme, but borders uncomfortably on apologia

The message that people who do awful things and are part of awful systems are people first is an important one both for combating the impulse to dehumanize the other and for achieving a proper understanding of how things get to the point where people can do and accept these systemic crimes
