The Popular anti-Semitic stereotype of Jews: a parasitic
monster, never participates in patriotic feelings such as
being part of a nation, such as Poland. After all, Jews
were welcomed. Recall the pogrom of July 4, 1946 in Kielce?
It took the historian Jan Gross (Princeton University) to
provide incontrovertible proof that Poles, not NAZIs, were
responsible for this pogrom, see the book "Neighbors".
