The tendency for Authoritarianism and Racism never really left Germany: remember, Nazism was stopped by outsiders, not Germans, so mostly they changed the symbols and stopped outright saying certain things even whilst still thinking and practicing them - doing what it takes to make it seem like they changed, not actually changing.

So it's no surprise that on a racially charged subject involving a Genocide were tens of thousands of children have been murdered for their ethnicity, the German Authorities not only in quite an extremely Racist way sided with the Genociders very overtly because of their ethnicity, but also moved back some more in the exercise of the power of the state towards doing things like in the "good" old days.

The mindset of Racism and Macht macht Recht never actually went away.
