I don’t mean to make this a debate on whether or not Poland was very accommodating to the Jews, but I’ll go with historical fact on this one.
There was a reason that most of the Jewish population was concentrated in Poland leading up to World War II and it wasn’t because Poland didn’t welcome them within their borders.
I’m sure there were Polish people who hated the Jews like other people who hated the Jews. I’m sure there were Germans that were accommodating towards the Jews even though the government wanted to exterminate them.
Maybe I should clarify that the Polish government at that time, unlike most of Europe, was very accommodating towards the Jews in pre-World War II Europe.
