Imagine if I ran an ad which went something like "George Bush should take his negro lynching, anti-intellectual, pig feet eating, sister-screwing, wife beating..." before the farmer's wife then finishes the sentence: "... KKK-loving, right-wing freak show back to Texas where it belongs."
Mine's slightly more over the top than the actual Club for Growth ad, but it's no more incorrect. For some reason it's perfectly valid to make just about any regional stereotype about the Hollywood and Northeastern "elite," (which, we should remember, was just code for "JOOs and Negro-lovers"), but people get all sensitive when one stereotypes the South and Texas. I don't think such regional stereotypes are particularly enlightening or useful, but nor do I think their invocation should provoke the kind of outrage that genuine racism should. But, why the double standard?
Of course, the amusing thing about the Club for Growth ad is how wrong it is - Vermont is not part of the "elite Northeast" to the extent that it exists, it's a small rural farm state.
...for the record, Vermont has precisely two Starbucks for all those latte drinkers to go to.
