I don't know why you have been getting downvoted, as that part seems to at least have a core of truth, as I just checked.
While not the inspiration for the pogroms themselves, the US segregation laws seem to have been at least reviewed while drafting the texts of the Nürnberger Gesetze, which would become the legal framework for persecution of Jews and other persons based on race in the Third Reich.

But that's not about the concentration camps dustyData was talking about, but about the "Lebensraum" doctrin to conquer the eastern European areas.

Completely different thing.

Concentration camps have been around in Europe already decades before the Nazis came to power, take the Russian Gulags for example.
Even the name the Nazis used is not new, the first camps called "Konzentrationslager" (the German name for concentration camp) were situated in the German colonies in Africa during the Herero massacres already in 1904, while the segregation into ghettos in Germany and much of the rest of Middle Europe, especially regarding the Jews, goes back to the Middle ages.

What dustyData proclaimed is just plain wrong and one of the fake ideas that might in some form be used to relativise, downplay or pass of guilt. Just the kind of buzz that current day fascists like the AfD in Germany are happily spreading.

but it’s also true

Nope.

Konzentrationslager (concentration camps) have been a tool for the Germans under that exact name since colonial times.
Segregation of the Jews into Ghettos (and frequent blaming them for stuff and even killing them in local pogroms) has been common practice since at least the Middle ages in Germany, centuries before the US even existed.

A tale like "we only got the idea because we were inspired by the Americans" is not only wrong, but also dangerous, as it plays right into the hands of the far right, which is currently actively trying to downplay the Holocaust and the responsibility of the German people during the Third Reich.
