I plead guilty on both counts.
But again I ask, why is it permissable to portray rural Southerners as bumpkins, and yet impermissable to poke fun at the intellectual capacity, vocabulary, or social skills of other ethnic groups? And don't tell me Sanford & Son was a sort of black Beverly Hillbillies. For that to have been a parallel situation, Redd Foxx's diction would have consisted solely of ebonics ("I be tired", "I be hungry") and liberally sprinkled with "mofo" or worse; sight gags would involve fried chicken, watermelons, enormous boomboxes, and much shuckin' and jivin'; and the sound track, rather than banjo picking, would have been whatever precurser of rap which existed at the time. Do you think such a format would draw criticism?
Better yet, do a Beverly Hillbillies in reverse. A family from Beverly Hills, members of an ethnic group so protected by political correctness that it cannot even be mentioned, falls upon hard times and has to move to the East Tennessee mountains. Instead of "hooo whee!" it would be "oy vey!" about every fourth line. They would all complain that people in Tennessee "don't know from good brisket"; they would "schlep" from one place to another, and of course they would constantly remind each other never to pay retail, even at the gas station. And instead of battered straw hats, they would all wear yarmalukes 24/7. Of course, this scenario, too, will never see the light of day, not least because it would insult the ethnicity of many writers and producers.
Nope, there's only one ethnic group for which this kind of crude ridicule is still permitted. As a thin skinned, sourpuss Anglo-Saxon, I wouldn't seek to ban the airing of reruns of The Beverly Hillbillies, or, worse yet, The Dukes of Hazzard. But let's just say "we are not amused."
