My Christian aunt carried one of those tattoos from Auschwitz. Only survivor of her family. I only mention she was Christian to let others know that, while it was at it's core a jewish extermination camp, others were targeted too. When they come for one, they come for all.

No, they did not come for all. They came for Jews (who they planned to completely exterminate), gay people, gypsies, and anyone who helped them or in any way defied the Nazis.

They came for my white Christian aunt because she was slavic. Slavs were the largest ethnic group targeted by the Nazis. Most were Jewish but not all.
