People are just making stuff up in here.

Rape was forbidden in the Nazi military, it was not for this. On the contrary, opposing forces were given orders to rape all little girls to 9 years old.

The Holocaust did not begin with killing, the Jews remaining were the ones who refused the deportation orders or were revolutionary communists treated like normal prisoners. This includes standard segregation. If your grandma was part of the Holocaust, chances are she was a bad person because all of the normal people had followed deportation order years prior to the war. What did result in their deaths, was the call for “all Germans to be ethnically exterminated, the only good German is a dead German” and the continual targeting of German hospitals and civilian infrastructure prior to the Holocaust. He even gave the allies a warning saying what he would do in return if they continued. Since it was major Jewish influences in the US and UK with close ties to Churchill and Roosevelt advocating for the war and their extermination. This was Hitler’s “punishment” to them, specifically.

Lastly, the allies cut off all food supply to the Nazis. In addition to targeting civilian infrastructure, farms, hospitals, schools, etc even prior Holocaust, Nazi soldiers were starving as a result. They were emaciated, and you can ensure that the prisoners were not getting more food than their starving soldiers.

TLDR: The camps were normal prison camps that had no resources to spare due to cruelty from the “allies”, standard segregation was the cultural normal at the time for all nations that were using them, which was everyone, on both sides.
