I remember when I was very young watching The Ed Sullivan Show, which was a very popular one-hour Sunday night staple for many years, and there would regularly be comedians on it telling "dumb Polack" jokes. Polack of course is a slur referring to Polish people. They would repeatedly use the word "Polack" and sometimes entire routines were based on "Polack" jokes. I was way too young to be racially aware then but would be willing to bet that it was nothing but Jewish comedians telling those jokes.
Off on a tangent a bit, but the Beatles went on The Ed Sullivan Show for three consecutive weeks early in 1964 and it was a huge event, replete with the screaming girls in the audience that for years were a fixture everywhere the Beatles went. This was just a few weeks after the JFK assassination and it served as a way to help the country get over some of the trauma of the assassination and the national grieving that went with it, an event which still reverberates very strongly today given that in retrospect it was a coup to forcefeed the Permanent Cultural Communist Revolution and the rest of the anti-White, globalist agenda on Americans and the West.
