I understand what you are trying to say, but the problem for me remains here: “Some people still believed the racist Nazi ideology, but they kept it mostly to themselves”. This isn’t enough, it may be progress, but it’s just not enough! If we have people believing it then that belief remains as fuel waiting to be consumed, and when someone like Trump appears and offers to allow that attitude again, they respond. In fact, 70 years after the Holocaust we know again have people addopting Nazism. So, how do we socially condemn racism, but also convince people it isn’t okay?
