If you’re interested in what those who criticize people like the scholar mentioned in the article have to say, I can provide some background (I live in Poland). Basically many Poles feel like they’re being framed as perpetrators (as a whole nation) instead of victims (6 million Poles were killed during WW2). There were many people who helped Jews during war. Among Righteous Among Nations Poles are the majority. Also some historians, like the one from the article, are considered to be biased by neglecting the majority of sacrifices of Poles while showing only wrong doings of some minor groups, which were never supported by Poland as a country. At the same time they fail to mention the scale of collaboration among Polish Jews during WW2 and after, which very often was punished by death by the Polish Underground Government.
