A democratic society agrees on laws, that can be changed through a certain process. Germany decided that not only the parents are responsible for the education of the next generation, but also the government. Therefore the equivalent to the US child protective service has the right to enforce that law, just like in the US, where kids are separated from their parents if they break the child protection law. This has nothing to do with kidnapping.

All I am saying is that kids have rights too. And it's society as a whole who defines those rights and provides government with the rights and means to ensure those rights are provided to the kids, even if this means to separate them from their parents.

Just a side note on state sponsored kidnapping:

> While a court order in June 2018 required the Department of Health and Human Services to reunite more than 2,700 children in its custody with their parents, that number is only a "subset" of the overall separations, said Ann Maxwell, an inspector at the HHS inspector general’s office.
