In my view, this cultural and social memory makes the Germans less insane on the topic of privacy, not more. We can see very well how in most of the modern world how insidious the process is. We make small concessions, little by little, and soon we live under total surveillance. It doesn't seem like that long ago that using your real identity on the internet was considered unwise. Now people are voluntarily giving deeply personal information to shady operations such as FB.
I hope the Germans are not convinced by people like you, and that they remain healthily paranoid about privacy. It's one of the things I appreciate the most about living here. I feel the laws actually protect me against the bad guys on this topic.
