I also live in Germany, and can share your view 100%: nobody is concerned here. I wonder however, if the reason is just because they don't understand the implications. For the regular person, this looks just like "they are doing something to fight child porn, and since child porn is bad and they're fighting it, it must be OK". The only way to change this situation is to get people to understand what's really going on, and that's a big challenge because the issues are not only complex but often highly technical.
Probably, the real problem is that achieving this requires really good communication skills, and this is something we geeks don't excell at. Looking around /., I see that many regular contributors here have an absolutely condenscending attitude towards "average Joes". But when dealing with issues such as this, which are essentially political, it is mostly average Joes who cast the votes, so you'd rather take them seriously and find a way to communicate with them.
Until we understand this and act accordingly, we'll continue to see the decisions we care about being made in the wrong direction by clueless or even ill-intentioned politians.
