Those countries may not have been just like Nazi Germany, but they still had Fascist dictatorships. The fact that there have been dictatorships in Italy, France, Austria, Spain, and Hungary shows that Catholic Righties are susceptible to Fascism just like Protestant Righties. The Spanish Right sucked up to Franco just like today's American Right sucks up to Trump.
Even today, look at where Fascism is rising in Europe. Hungary already has a dictatorship again.
I think arguments can be made for Catholicism or Protestantism being worse when it comes to resisting Fascism, but at the end of the day, religion in general is bad for us, good for Fascism.
Poland enacted the same kind of laws as Nazi Germany had in the 1930's.
They limited Jewish entry into colleges, government jobs & jobs of power like Lawyers or Doctors.
They also segregated Jews sometimes too see Ghetto Benches.
Even so, Poland ended up having the most who helped Jews in WW2.
Zegota, Highest number of Righteous Among the Nations risk their lives against Europe's ONLY death penalty placed for saving Jews in Poland.
Some Poles died for helping Jews, most notable being Henryk Slawik, who saved 6,000 Holocaust victims with fake passports, Henryk Slawik also was hanged by Nazi Germany in the end for it.
Then there's Poles like Jan Karski, Witold Pilecki & Stefan Korbonski who warned the World about the Holocaust.
Truth is, most Poles weren't subservient killers like Germans.
Poles actively created the biggest anti-Nazi resistance in occupied Europe, called Armia Krajowa.
There are few examples of Poles being Nazi collaborators, but few & far between.
Actually, more Poles fought with the Soviets in WW2 than with Nazis.
Yes, most Poles didn't fight for Soviets either, but with Armia Krajowa.
