No excuse, though Milo!
You don't throw out the baby with the bathwater, do you? There were plenty of valiant Poles during WWII along with plenty of stinkers! There were scores of
Jews who were truly innocent, others, who (Holocaust or no Holocaust) were criminals, just as with any other people.
The reality is that the Jews had been deemed by demagogues throughout Germany, from Stoecker and Ahlwahrt up through Hitler himself, as some foreign host body invading the host organ and other assorted bilge.
The Enlightenment failed in Germany to take root as it had in France or England, thus, the soil was rife for foul-mouthed haters to spew their filthy message of survival of the fittest, eliminating the "weak", and muscling their way into communities like a human juggernaut, destroying everyone in their path, truly like heathens, barbarians without a scintilla of human conscience, worse even than the most savage animals.
Sorry there, Milo. No rationalizations justified.
