Earlier this month, Fox News commentator Bill O'Reilly found himself on the other side of the firing line for having used the term "wetback" in a discussion about illegal immigrants on his nightly program, "The O'Reilly Factor." Indeed, the uncomfortable position in which this puts the pugnacious host is pure poetic justice: For seven years, the former "Inside Edition" anchor has brought a brand of dyspeptic discourse to the airwaves, lording over a talk show that's as much about his bully tactics as it is about the issues of the day.
