The Thanksgiving holiday seems like one of those rare occasions in American life where virtually everyone shares a similar experience, the traditions of the family gathering, the food, the football, the sometimes contentious discussions among people who love each other but nonetheless have different worldviews and political beliefs. It's become something of a cliché, in fact, with an annual flurry of tongue-in-cheek articles in newspapers and other publications giving advice on how to handle that obnoxious uncle's unpopular opinions at the Thanksgiving dinner table. And yes, these articles are usually aimed at liberals trying to deal with that drunken Limbaugh-listening relative who insists on baiting everyone at the table by going on about the pet right-wing outrage of the moment and passing on talk radio propaganda as if it had been delivered directly from God.
