As one of Polish heritage, my pet peeve is when they are referred to as “Polish Death Camps”, it happens all the time, and I suspect the people that do it, have a hidden agenda when they refer to them as such.
I hope it is a comfort to you to know that as an older person who grew up in the Baltimore-Washington area and has stayed well-informed all my life, I have never heard that term used except as a way to indicate the location of a particular camp; although I am aware that Poles were targeted as well as Jews, gypsies and homosexuals. My perception was that most of the camps were in Germany.
