That wasn't what I was (and still is) taught in school in Germany.

The blame was always squarely put on Germany. It was always stressed that most of the German population had more than an inkling of what was going on and many agreed.

The first time I heard the term "polish extermination camps" was a few years ago when the Polish Government outlawed it.

So I'm really at a loss here.

For such claims you really need to provide solid sources. I have never encountered this sort of "blame shifting" (schooled in East Germany in the 80's, but I also never heard that from the "other side").

The only sort of blame shifting related to Poland that I encountered in East German propaganda was that the Katyn massacre was blamed on Nazi Germany, not on the Soviet Union.

Of course there are extremely far right organizations in Germany which to this day try to deflect the blame, but they are a minority and don't influence the public discourse (unless you live in their bubble of fake news and propaganda of course).

But in general I don't see why nationality matters much in this case. When talking about persecuted Jews, communists, homosexuals (or any other group persecuted by the nazis) of course this also includes Polish Jews, communists and homosexuals.

The German government had reiterate the German responsibility continuously, in words, diplomatic action and payments for the surviving victims. The Polish government however has decided lately on line of denying their share in the war crimes, effort that includes anti-historic legislation.

Where did you get that idea? I'd say if you'd claim something like that in public in Germany, you can kiss your career goodbye.

Which German government do you mean ? There were 2 at that time.

This is absolute nonsense. We are all very much aware that it was us, the Germans, who did this.

Nobody in germany generally calls them "polish death camps" and nobody thinks poles are in any way to blame. Even if you called them polish deaths camps, people would assume you mean the Nazi concentration camps on occupied polish land.
