Welcome to FreeRepublic, Pomian!
Because you are new here, please, allow me to step forward to say to you that the majority of FReepers *love* the Polish people. Poles are our FRiends, and we have been praying for Polish families and troops fighting beside the United States' in the middle east.
That said, all four of my greatgrandparents were born in Poland. I have always been proud of my heritage. Polish jokes have never offended me, because I grew up in a predominantly Polish town. Thinking back to my childhood, the majority of people who told Polish jokes were Polish-Americans. That is just my experience.
The only groups of people that you'll see FReepers making fun of are the ones who are selfish, self-centered and have no hearts -- for example, most Democrats and the French. FReepers know that the Poles are loving, faithful, faith-filled people.
