That story reminds me of something one of my teachers told me about his experience as a child in Germany during WWII. As children were indoctrinated and parents could get into trouble for things they said, his father was very careful in his talks with him on walks, which he described to me as "deprograming" though his father was careful about what he said. I think he also conveyed the idea to his son that he needed to keep his mouth shut to stay safe.

It must be horrible to live in a place like that, but if one does, it is often wise to keep one's thoughts to oneself and not make public declarations.
