I invite you to Dachau if you want a tour there. Dachau never was a formal extermination camp, but it was the concentration camp after which all other concentration camps were modeled and then modified. Maybe after a tour there you learn to be quiet about things you don't understand.
Please don't cross into personal attack. If someone is wrong and you know more, sharing some of what you know might help us all learn something. Just putting down their lack of knowledge only makes this place worse.
Hey guess who's Polish (sorry to burst your bubble there my German friend)? Has spent large amounts of time researching the atrocities of the Holocaust? And has been to Auschwitz (I guess they wanted to keep the fumes of the human corpses outside of their homeland.)
