I don't get why Jews are complaining about the Nazi concentration camps. They got such a warm welcome.
Is this meant to be a joke about the Holocaust?
No, don't you know about concentration camps? People were brutally murdered.
It's good that you accept the brutal reality of the Holocaust and recognize it as a crime against humanity.  However, the first thing you said to me sounded like it was a joke, and such a thing could be very hurtful to people whose grandparents might have died in the camps.
