A significant portion of the Polish country was anti-Semite as well, however.
Rounded up escaped Jews and turned them back over to the German guards.
There were plenty of Ukrainians, Lithuanians, Romanians and others as well as Poles that murdered Jews. Poles were far from the worst, with perhaps several million Poles involved in rescuing Jews, as is noted in Israel’s Yad Vashem.

And there was a loophole. All a Jew had to do to be accepted was conversion to Christianity in some form. Before the Nazis, that also worked in Germany, to the point that some high-level Nazis with partial Jewish ancestry got special exemptions. Hitler’s family’s fully-Jewish doctor wasn’t a Nazi, but got a special visa to leave, anyway, because of his personal connection to Hitler. But anyone who wasn’t connected to a high-level Nazi got the chop. https://en.wikipedia.org/wiki/List_of_Nazis_of_non-Germanic_descent
Hitler has to be the first would-be world conqueror who slaughtered entire peoples for purely ethno-racial reasons. Most conquerors required but one thing of their subjects - demonstrated loyalty. If Hitler had demonstrated the open-mindedness of William II, Europe might be speaking German today.
A significant part of the Polish people are STILL antisemitic.
Every country in Europe was anti-semitic, even the US.
Poland is singled out, simply because they had the most Jews in Europe.
But if Poles were so anti-semitic, why did so many Jews settle there over the centuries?
Some did, yes, but not a "significant portion" even of the anti-semitic Poles
