I’m just goint by my wife’s family’s experience.
They were helped out, hidden, and finally smuggled by Polish neighbors -— who boxed up all their stuff (including a very valuable silver menorah) and shipped it all (along with 100% of proceeds from sale of house in abstencia) to her in the USA, post war.
Paid the shipping, too.
(As an aside, they immigrated — with much hardship because of Soviets — and again lived next door to my wife’s family.)
I have never been to Poalnd, but I have a very soft spot for the country.
I do too, for other reasons.
Poland has a good history of ( mostly Catholic) moral spirituality, and there were Germans too who helped Jews at great risk to themselves...priests and nuns sent to the camps.
I think we can find good and hate in all groups of people, IF they are given the opportunity to show goodness and morality. Unfortunately there are millions of Muslims who are not in an environment where there “goodness” is allowed to flourish...again the political ideologies that are the ‘problem’ ( and one too few americans are willing to accept).
