Many people will have you believe that Polish jokes result from the Polish themselves. This is because they didn't know the language when they emigrated and refused to assimilate. Those statements are excuses and blaming the Poles themselves. Please do not believe them.
I came across quite a few of those in readings. Blaming victims of hate speech is quite disgusting. Imagine if we did that to any other group?
Polish "jokes" came from Nazi German propaganda pushed ironically by Soviet communist sympathizers in Hollywood.
These were a combination of two despicable ideologies, and those who made these jokes perpetrated propaganda. If you do today, you still are. Ironically, I saw one come from an Israeli newspaper, so, in a sense, they are once again collaborating with the Germans.
The article was about so-called Polish collaboration, another hypocritical assessment of co-victims, scapegoating them for their crimes.
The racist stereotype that Poles are intellectually inferior or have subhuman intelligence originated from Nazi German propaganda and Soviet propaganda.
For example, the myth that a major group of Polish horses was used to attack German tanks in World War II was total Nazi German propaganda. The Nazi Germans repeated this myth until it took a life of its own using the "Big Lie" technique. Germans were masters of propaganda.
The whole quick invasion is a myth. The Germans took a rather heavy toll fighting the Polish; one must recall the Poles were then invaded on the eastern front. The Polish could not win against the Germans.
The Big Lie is "the intentional distortion of the truth, especially for political or official purposes. Adolph Hitler wrote about this tactic of trying to deceive a country's citizens. ["The great mass of people will more easily fall victim to a big lie than to a small one." Adolf Hitler (1889-1945), Mein Kampf, Vol. 1, Chapter 10, 1925].
The Soviet Communists saw the value of this myth and the racist notion that Polish people have subhuman intelligence, so they had their Left-Wing sympathizers in Hollywood push it to the American public using Anti-Polish Television and Movie imagery.
The image of Polish people having subhuman intelligence was useful to the Soviet Communists. People would not mind too much if the Soviet Union occupied Poland if Poles were portrayed as having a Slavic culture that is inferior and less human.
Indeed in the West, there were also many communist sympathizers and many in Hollyhood; with that, they could push the skewed narrative of the Poles. "A Street Car Named Desire" is an excellent example of how Poles can be manipulated into subhuman thugs.
The German Nazis (and even the Soviets) killed Poland's educated class first to make their racist stereotype of "Poland having inferior intelligence" their reality.
Although it clearly did not work, we can see how many Poles of great intelligence have lived on.
The Nazi Germans also felt "Poles only had the intelligence for Nazi slave labor."
Polish "jokes" were in Hitler's two speeches after he invaded Poland.
Hitler ridiculed Poles in his Sept. 19, 1939 speech in Danzig (today called Gdansk) and in his Berlin speech on Oct. 6, 1939, with these hate-through-humor anti-Polish "jokes" and references.
Michael Preisler, a Polish-Catholic survivor of the German Nazi concentration camp Auschwitz (Auschwitz prisoner #22213), has repeatedly stated how the Germans ridiculed the Polish people as having less than human intelligence. Polish jokes were quite popular among guards in the parts of the German death camps where there were Polish Catholic prisoners being tortured and killed.
Ironically, Left-wing Hollywood and the TV Networks (like NBC-TV) pushed these racist Polish "jokes" even though Hollywood claimed to hate Nazis. Hollywood and NBC-TV hate Nazi propaganda, but not when it applies to Poles.
Hollywood and Network-TV (NBC) deeply hate Anti-communist, Pro-American, Pro-Catholic Poland. The Polish American Guardian Society has documented NBC-TV's attacks on Poland with racist Polish "jokes."
The recent movie "Katyn" shows the German Nazis and Soviets killing the educated Polish class in Poland to make Poland "intellectually inferior" and easier to rule. This was during the time Nazi Germany and Soviet Russia were Allies and were collaborating to destroy Poland as per their Molotov-Ribbentrop pact to destroy Poland together.
Although there were degrading jokes about all ethnic groups in the United States due to assimilation problems when they arrived, the jokes that portray Poles as having subhuman intelligence did not predate the 20th Century in America. Racists introduced it in Hollywood and on TV networks like NBC-TV in the late 1960s and 1970s. Imagine making jokes about Jews as they did about Poles?
Many Polish Americans who lived before this time have reported that they never heard these racist subhuman intelligence jokes about Poles until after they were introduced by Left-Wing networks like NBC-TV in conjunction with Hollywood. NBC-TV launched Polish-bashing shows such as "Laugh In," which ridiculed Polish people constantly. Polish Americans felt the producer of "Laugh In," George Schlatter, was an Anti-Polish bigot. In addition, late-night bigots were encouraged to bash Poles with "jokes" that portrayed the Polish people as having subhuman intelligence.
Therefore the power of Television and motion pictures was used to demean and dehumanize Polish people with repetitive Big Lie type propaganda.
So the anti-Polish hate really blew up at this time. Propaganda was carried on by Hitler and the Soviets.
Anti-Polish movies such as "The End" were some of the earliest movies meant to degrade Poles with racist humor. In addition, other anti-Polish shows, such as "All in the Family," were used to degrade the Polish people even though the left-wing producer claimed the ruse that the show was supposed to be "against bigotry."
"All in the family" was filled with racist anti-Polish sound bites such as "Dumb Polak" in an attempt to influence its viewers to have the same anti-Polish prejudice that the Left-wing producer of the show (Norman Lear) had.
So basically, Polish "jokes" were part of a Hollywood/TV media hate campaign against Polish people.
We need to assess this and how Hollywood, an institution that claims to be anti-racist, propagated such vile hatred against the Polish.
We witness the vile hypocrisy of individuals promoting the ideology of Hitler.
