But when Poland regained its independence in 1919, thanks to the Versailles Treaty, the nation degenerated into military dictatorship, and much of the population was antisemitic.

No more than any other European country, just another lame attempt to paint all Poles as anti-semitic.

Well, didn't you know? I'm Polish, I was born with an anti-semitic gene. Not my fault. Someone forgot how Poland was a haven for Jews for hundreds of years.
Suprisingly most of the people that are Righteous Among the Nations are Poles.
It's, good that my grandma (Warsaw uprising medic) didn't live to read/hear this crap.
