Not all things have to be related back to the Holocaust. A concentration camp is a concentration camp, "a rose by any other name" and all that. Not all of the German camps were death camps. All the camps were heinous places and immoral, just as our detainment camps housing the children on the border are today.
That is what happens when you privatize interment facilities. Vetting of employees is substandard and oversight is lax. We had Interment camps during WWII which were immoral. Conditions may have been better than the camps in Germany, but still immoral. A concentration camp is a concentration camp regardless where it is located
