I think there's a misunderstanding happening here. You seem to be suggesting Auschwitz get bombed assuming it would not blowing up the Jews (and gypsies, and homosexuals, and others that made the Nazi list of "deviants") being actively imprisoned, which sounds great but would have been unfeasible. The previous reply doesn't seem to be asking what would be specifically helpfully in blowing up Auschwitz. I think it's unanimous "that factory of death was bad and making it stop is good, " so I think it's more like they're taking into account how dropping bombs in WWII actually worked, which was a pretty imprecise process. Ultimately, bombing Auschwitz would also have blown up the people held prisoner in Auschwitz, and those people might not think being blown up was super helpful for them, regardless of whether Auschwitz was destroyed in the process.
