Being offended doesn't take any intelligence. Besides, the joke only hurts if its true.
That's not true. As Hitler said, if you repeat something over and over and over and over and over again, especially something ABSURD, a LIE, it gives the apperance of BEING TRUE. Especially when this is done in mass media like TV or motion pictures. Its called "the Big Lie" technique.
This is why in the 60's and 70's when the Hollywood-NBC-TV media complex introduced and repeated over and over and over subhuman intelligence jokes about Polish people, American people who were surveyed (who did not live near any Polish people) who said they DID NOT KNOW any Polish people, BELIEVED Polish people had inferior intelligence and should be treated accordingly.
Why do you think Jewish groups and Black groups fight so hard NOT to hear untrue jokes about Jews being Rats, or Blacks being Apes, in mass media like TV???
I would love to see you say that untrue Rat jokes about Jews are OK, to a Jewish person's face, since they are untrue.
I would love to see you say that untrue Ape jokes about Blacks are OK, to a Black person's face, since they are untrue.
