Again you are doing it. We have agreed that the camp leaders may or may not have understood what was going on. They didn't recruit people to the camp. By your own words you have said that the people running the camps might not have understood what was going on.
But lets go back to the numbers shall we.
8 million people live in NYC. So if 6 million people died lets say the equivalent of rounding up everyone who lives in NYC and sending them to camps.
If this was an aim to just "house" people then it was a very poorly thought out plan. Think of the disaster at the Superdome 2300 people were trapped in the Superdome without resources, look at the results.
Anyone who decided to "house' people in camps would have understood that great expense and problems that would occur. Just feces is a huge problem. So why would they do this the way they did if the intention was just to house them in the camps during the war?
Just explain your opinion on that.
What movies do you think they watched?
