As Goebbels pointed out, all it takes is the right kind of threat, either real or manufactured ("Think of the children!"), and those "transparency movements" you speak of will fade out more rapidly than the grandparent post.
How does one do that?
Well, I don't know if this is still done today, but when I was in 7th or 8th grade, they (school) drove us, by the busload, to visit a concentration camp.
We were shown the lampshades and wallets made of human skin. The place to stand where inmates would be executed during what they thought were medical examinations. And so on and so on.
It is quite possible that the next "Western" genocide will happen somewhere in Europe. But as somebody who has grown up here, I can assure you it won't be in Germany.
I just wish that history was thaught like this everywhere.
But the tolerant and open minded strain is pretty dominant. Germany is 9% foreigners. Frankfurt is like 30%
