...It might be that the "Polish Joke" actually originated in part from Polish people themselves, trying once again to get through the adversity of trying to assimilate into American life."
These anti-slavic Poles!!!
Already mentioned this above. That is from the book by Christie Davies, Mirth of Nations. He is basically one of the only scholars to purport that opinon, and on closer inspection of his book one understands why: it needed to fit into his thesis that self-directed (and in my opinion self-congratulatory) laughter is a sign of intelligence, in his words as exemplified by the Scots, the English, Jews, et al. But most importantly, he makes a distinction between ethnic jokes and ethnic slurs.
"Throughout the book, a main theme is Davies's demonstration that ethnic jokes are playful, that they are not expressions of aggression, and that they do not create or exacerbate hostile tensions between peoples or groups ...For instance, in Europe there are many ethnic slurs against the Poles, but very few Polish jokes. In the United States, the land of the Polish joke, there are very few ethnic slurs against Poles."
Mirth of Nations, Page 158-159
"(American Polish jokes) is a world apart from the earlier folklore of Eastern and Central Europe, which constituted a veritable system of ethnic slurs expressed about the Poles by several different peoples who had been involved in long-lasting, and very violent, national and ethnic conflicts with the Poles .... Mild snobbery is quite distinct from real hatred. Germans, Russians and Ukrainians have a long history of hating and slaughtering Poles. Americans do not."
Lol. Even your favorite and only source comes out and says it. I really give up on you now.
Good night.
added note: However, Davies seems determined to absolve himself from any similarity between the violence of Eastern European history and ethnic slurs in comparison to the "playful" British ethnic slurs between its historic neighbors is discussion for another thread, and another day.
