One of the aspects of the Holocaust, and that stereotypical “German efficiency”, is that prisoners were worked to death. They were trying to squeeze every last bit of energy out them for the benefit of The Reich. So even those with useful skills were ultimately destined for the ovens. They took their houses, their businesses, their clothes, their hair, their gold fillings, their labor, every bit of “use” they could get out of a human life. If the Nazis had invented some kind of sci-fi machine that reduced a body instantly to its individual elements for industrial purposes, you can bet they would have done that too.
Gutfeld’s comment is a good example of how the party of “all lives matter” doesn’t care about lives at all.
