The German government has become what they claim to oppose. Totalitarianism. When your people cannot call out a government, when the government can squelch criticism you are entering a scary state of affairs.

The truth is, far to many people are all to happy to lord over people they don't like. People that are different. It's sick but true. We aren't really taught that the villians usually think they are the good guys. It's what makes them so sure of themselves.
