"Ignorance should not be an excuse, if they were not certain they should have learned more."
After many centuries of the most virulent anti-Semitism that is something which should be inscribed on the heart of every living Pole.
Over many centuries Poland was the main heaven for the persecuted Jews. Until Polish partitions, Jews enjoyed unprecedented religious freedom and autonomy (their own self-governing towns, own courts, even Jewish Parliament - thing unheard anywhere else).
If Poles managed to defeat Hitler in 1939, the Holocaust would not happen. You can blame Poles for their weakness if you wish, but even while they were much smaller and less amed than Nazi Germany, they were willing to pay paid horrible price in lives and treasure to put the fight.
Shame on you.
